Value Collection 201097P Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 201097P is a button socket cap screw designed for applications requiring a low-profile head and strong clamping force. Sized at 1/4-20 x 5/8 inch, it is fully threaded with a 5/32-inch hex socket drive. The screw is manufactured from alloy steel with a black oxide coating that provides mild corrosion resistance and a dark, non-reflective finish. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. This fastener is used by machinists, millwrights, and mechanical contractors in panel, bracket, and machine assembly work.

This button socket cap screw suits light to medium-duty fastening tasks where a flush or recessed head profile is needed and clearance is limited. The UNC thread form and Class 3A thread fit make it a standard choice for precision assemblies in industrial equipment, enclosures, and fixture fabrication. It is sold in a minimum order quantity of 100 pieces, making it appropriate for production line use or shop stock replenishment.

Key Features

Compatibility

Designed as a standard UNC replacement or stock fastener for any application requiring a 1/4-20 button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Installation is performed with a 5/32-inch hex key or socket bit driver. Always ensure mating threads are clean and free of debris before fastening. Do not exceed the rated torque range for the 1/4-20 thread size and alloy steel grade. Black oxide coating offers minimal corrosion protection — apply a thread lubricant or anti-seize compound in high-moisture environments.
