Value Collection 701118PR Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 701118PR is a button socket cap screw designed for fastening applications where a low-profile head and high strength are required. Sized at 1/4-20 thread with a 1/4 inch length under the head, this screw is fully threaded and driven with a 5/32 inch hex socket. The alloy steel construction provides a hardness rating of 36-43 HRC, making it suitable for demanding mechanical assemblies. A black oxide coating offers mild corrosion resistance and reduces light reflection. This fastener conforms to ANSI/ASME B18.3 and ASTM F835 standards. Machinists, millwrights, and mechanical contractors use this type of fastener in precision assemblies and equipment manufacturing.

This button socket cap screw is used in light to medium-duty mechanical assemblies where a rounded, low-profile head is preferred over a standard hex head. Common applications include machine frames, fixtures, jigs, enclosures, and equipment panels where clearance is limited and a flush or near-flush surface is needed. The UNC thread standard and Class 3A thread fit ensure consistent engagement with standard tapped holes. This fastener ships in single-piece quantity with a minimum order of 100 units, suitable for shop stock or production runs.

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 1/4-20 UNC fully threaded button socket cap screw with a low-profile head profile.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical technicians using a 5/32 inch hex key or socket bit driver. Ensure the mating tapped hole is clean and free of debris before driving. Apply appropriate thread torque per applicable engineering specifications for the assembly. Do not substitute a different drive size, as doing so can damage the socket recess.
