Value Collection 201094P Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 201094P is a button socket cap screw designed for fastening applications that require a low-profile head with a hex socket drive. Sized at 1/4-20 x 3/8 inch, this fully threaded fastener is machined from alloy steel and finished with a black oxide coating that provides mild corrosion resistance and a non-reflective appearance. The 5/32-inch hex socket drive accepts a standard Allen key or hex bit driver. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. This screw is used by machinists, millwrights, fabricators, and maintenance technicians across a wide range of industrial and mechanical assembly tasks.

This button socket cap screw is suited for applications where a standard socket head would protrude excessively or interfere with adjacent components. The low-profile button head distributes clamping load over a wider bearing surface compared to a flat head. Typical install locations include machinery guards, brackets, panels, fixtures, and equipment housings. The UNC thread standard and Class 3A thread fit make it compatible with standard tapped holes in steel, aluminum, and other metals. Sold individually per package with a minimum order quantity of 100 pieces.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen-style driver. Ensure the mating tapped hole is clean and free of debris before threading. Do not exceed the rated hardness and strength class of this fastener when selecting for high-load or shear-critical joints. Always verify thread engagement depth meets engineering requirements for the specific application.
