About Set Screw & Manufacturing
About Set Screw & Manufacturing
Set Screw & Manufacturing has a history dating back to 1935 and operates out of Elgin, Illinois, where it manufactures, imports, and distributes set screws and specialty fasteners. The company built a focused niche around a fastener type that general-purpose hardware suppliers often carry only in limited sizes and drive styles.
The product line covers slotted set screws, socket set screws, and custom specials made to print, giving engineers and maintenance buyers access to thread sizes, point styles, and materials that aren't always stocked by larger fastener distributors. This specialization has kept the company relevant to industrial buyers who need a specific set screw configuration rather than a generic substitute.
ChatMRO lists Set Screw & Manufacturing's socket and slotted set screws plus custom fastener options sorted by thread size, drive type, and point style so maintenance teams can find an exact match quickly. Searching by thread specification or point style (cup, cone, flat, or dog point) surfaces the correct in-stock or custom part.

Frequently asked questions
What is the difference between a socket set screw and a slotted set screw?
A socket set screw is driven with a hex key inserted into a recessed socket on the top of the screw, while a slotted set screw uses a standard flat-blade screwdriver slot. Socket set screws are generally preferred in tight spaces or where a flush, tamper-resistant appearance is needed.
Can Set Screw & Manufacturing produce custom fasteners not in their standard catalog?
Yes, the company manufactures custom specials made to print in addition to its standard slotted and socket set screw lines. This allows buyers to source non-standard thread sizes, lengths, or point configurations through the same supplier.
What point styles are available on set screws?
Common point styles include cup point for maximum grip against a shaft, cone point for permanent high-holding-power applications, flat point for frequent adjustment without marring the shaft, and dog point for alignment through a hole. The right choice depends on whether the screw needs to be removed and reinstalled or provide permanent locking force.
How long has Set Screw & Manufacturing been in business?
The company has a history dating back to 1935, giving it roughly nine decades of experience manufacturing and distributing set screws. It remains based in Elgin, Illinois.
Do set screws require a specific thread class for best performance?
Set screws are typically specified with a standard thread class appropriate to the application's holding and removal requirements, and material selection (steel, stainless, or alloy) affects corrosion resistance and strength. Matching thread class and material to the mating component helps prevent stripping or loosening in service.
