Buy Set Screws



Set Screws are also known as Grub Screws or Blind Screws. Set Screws are designed to hold an object in place via friction between the point of the screw and the fastened material. Set screws are designed to be used under compressive stress only. A common use of Set screws would be securing gears or pulleys to a shaft.

Fortunately, Ondrives.US has the ideal solution. Our tipped set screws are available in nylon or brass half-dog tips or silver solder oval tips. They are specially engineered to hold components in place without damaging shafts or components.


Order the nylon, silver or brass set screws you need today, request a quote, or contact Ondrives.US to learn more. For full specifications and Dimensional Parametric Search, see individual product listings.


We can provide custom tipped set screws, made to order to match your specifications. Contact an Ondrives.US application engineer to discuss your nylon, silver, or brass set screw custom requirements.


The soft nylon tip of these nylon tip set screws compresses on installation, conforming to the shape of the shaft and filling the space between the shaft and threaded hole. They cause no damage to the shaft, making them ideal for unhardened shafts. For best results, our nylon tip set screws should be replaced after each repositioning.


We can send free sample's set screws (5 pieces) of you wish of up to five types.As a manufacturer we deal with different types of small set screws, standardized under the brand name DELscrew.And you can buy them directly from us.These are the slotted set screws, also known as the grub screws.


There are two types of set screws, Slotted Set Screws and Hexagon socket Set Screws.For thin set screws of M2 or less, slotted set screws are suitable, and for thick set screws of M3 or more, hexagon socket set screws are recommended.


The shortest of set screw overall length is 2mm in JIS standard.For the set screw overall length of 1mm to 1.8mm, select from DELscrew.For the long overall length (6mm or more) set screws, I think that hexagon socket set screws is good.


The DEL standard is the set screws with a total length shorter than the JIS standard (B1117) for a slotted set screws.The DEL standard was originally provided by SAIDA Manufacturing Co. Ltd.Below, we will introduce the background of the establishment of the DEL standard and the DELscrew.


For example, the shortest total length is 2mm in the JIS standard slotted set screw, but there are times when you want a shorter total length.For the past 50 years or more, SAIDA Manufacturing Co. Ltd. has received orders for various slotted set screws and manufactured them, and we have been able to feel the situation in that area.


According to JIS standards, even thin set screws such as M1, M1.2, M1.4 and M1.6 have the shortest total length of 2mm.However, as a user, there are many cases where you want to use a set screw with a total length shorter than 2mm.


The JIS standard includes "Slotted set screws (B1117)" and "Hexagon socket set screws (B1177)" as headless set screws.By the way, the JIS standard for set screws with heads is "Square head set screws (B1118)".


Most of the commercially available set screws have a hexagonal hole in the head, and a hexagon wrench is inserted into it and turned. These are called the hex socket set screws or the hex socket grub screws.


For hex set screws with small diameter (less than M1.6), the hexagonal holes will inevitably become thinner.Then, the engage between the hexagonal hole and the hexagon wrench becomes smaller, and if you tighten it strongly, the hexagonal hole or the hexagon wrench becomes break down.(Smaller hex set screws than M2 is the unit price seems to be higher due to difficult processing)


The screwdriver used for the slotted set screw is the slotted screwdriver.On the other hand, the screwdriver used for the Phillips screw is the Phillips screwdriver.The Phillips screw is easy to use, but when tightened strongly, the screwdriver will be forced to lift up, making it easier to lick the cross hole.Most of the Phillips screws on the market are headed screws. There are some Phillips set screws in the market, but they do not exist in the JIS standard.


No new cam-type automatic lathes will be manufactured in Japan or around the world.More than 30 years ago, automatic lathe makers stopped manufacturing.Even in our factories that use automatic lathes, cam-type automatic lathes are almost gone.No machine that make set screw. No factory that make set screws


However, in a general cam type automatic lathe, the threaded part is machined with a thread cutting die.Depending on the way it start machining the thread cutting die, the accuracy of the coaxiality between the tip of set screw and the threaded part may drop.Until 1986, even at our company, the threaded part of set screws were machined with thread cutting die, so we had a lot of trouble maintaining the quality of the set screws.I don't want to go back to that time again.


It is possible to make the slotted set screws with NC automatic lathe, but it takes two to three times as long as a cam type automatic lathe to make one.In terms of cost competitiveness, it is not an enemy of cam-type automatic lathes.


In the olden days (until the mid-1970s), machine tool makers made cam-type automatic lathes that made "screws with slotted".However, due to the trend of the world, "screws with slotted" have moved in the direction of not being used.


Assembling using "screws with slotted" is laborious and costly.Therefore, equipment manufacturers use "screws with cross-recessed" instead of "screws with slotted".The set screw has changed from "Slotted set screws" to "Hexagon socket set screws".


For that reason, the number of "screws with slotted" themselves has decreased considerably.However, even now, mechanical wristwatches still use the beautiful "screw with a slotted" of the minus part that has been polished.


Machine tool makers haven't produced cam-type automatic lathes suitable for making "screws with slotted" for a long time.Cam-type automatic lathes that make "screws with slotted" are only old machines made in the past.The factory that makes screws uses old cam-type automatic lathes are being repaired and used.


Factories that manufacture set screws continue to use cam-type automatic lathes that were built 40 or 50 years ago.With an automatic lathe that continues to work 24 hours a day, the rotating and sliding parts wear significantly.In order to repair the wear, machine tools such as ordinary lathes, surface grinders, cylindrical grinders, drilling machines, vertical milling machines, and horizontal milling machines are required, and people who can master the machines are also required.


However, the current situation is that factories that manufacture general set screws do not have those machine tools.To use a machine that has been heavily worn, it requires the advanced skills of an automatic board craftsman, but craftsmen with such advanced skills are getting older, and younger craftsmen who follow are rarely appearing.


There is also the issue of successors to the factory owners who make the set screws.The president's son doesn't feel like taking over at the factory that makes set screws.Even if you want to rejuvenate your employees, few young people today are trying to get into the industry and hone their skills.


As a result of changing from cam type to NC type, the number of cam type automatic lathes has decreased in Japan, and among them, the number of cam type automatic lathes that can manufacture slotted set screws has decreased.


In the case of threading with the turning tool, the "screwless product" occurs only due to the missing the turning tool tip.The turning tool tip loss does not automatically recover, so it does not cause quality variation.In addition, "incomplete screw products" in which the screws are only partially machined will not occur.In other words, stable quality can be ensured without variation.


The hole of small diameter hex socket set screws can all too easily crack when the screw is being tightened.Our hex socket set screws are made of Ni-Cr-Mo Steel (JIS SNCM240). Furthermore, the manufacture is high-precision.


Through heat treatment, we have made the hardness to be high on Rockwell Scale C (HRC50 - 53) as well as coferring high durability.The hexagonal hole is as tough as you can handle, and if your hexagonal bar spanner gets stuck during overtightening because the handle snaps (see the diagram below), it can be removed by magnet, because the hexagonal hole of our hex socket set screws does not deform.


For rustproofing, our hex socket set screws are surface treated with a black oxide film and then dried with a hot air vacuum dryer.These screws will thus be suitable for automated assembly because they need not be oiled; at the very least your assembly workers need not get oily hands.


The sharp part in the center of the CC point protrudes about 0.1mm to 0.2mm from the circumference of the dent.Therefore, as you tighten the screws, the pointed part of the tip will bite into the other party before the circumference of the dent.


M5 set screws are used in a variety of products that we offer, from pinion gears to hubs to collars. The cup point of the set screw is able to dig into the shaft that it comes in contact with to create a sure hold.
