Value Collection 701135PR Button Cap Screw 1/4-28 X 7/8

Product Description

The VALUE COLLECTION 701135PR is a button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Sized at 1/4-28 UNF x 7/8 inch, it is fully threaded and driven with a 5/32 inch hex socket. Constructed from alloy steel with a black oxide finish, it meets ANSI/ASME B18.3 and ASTM F835 standards and carries a hardness rating of 36 to 43 HRC. Mechanical contractors, millwrights, equipment fabricators, and maintenance technicians use this fastener where a rounded, flush-style head is required and clearance is limited.

This screw is suited for light to medium-duty mechanical assemblies, machine guarding, brackets, panels, and general structural fastening where a button head profile is preferred over a standard hex cap or flat-head style. The black oxide coating provides mild corrosion resistance and a matte appearance commonly specified in industrial and OEM assembly environments. Minimum order quantity is 100 pieces; individual package quantity is 1.
