Value Collection A997064 Button Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION A997064 is a 1/4-20 x 2-1/2 inch button socket cap screw manufactured from alloy steel with a black oxide coating. The button head profile provides a low-profile, rounded appearance suited for assemblies where head clearance is limited. Drive engagement is through a 5/32 inch hex socket. Threads are fully cut to UNC standards with a Class 3A fit, delivering close tolerances for secure, repeatable fastening. Hardness is rated 36-43 HRC, making these screws suitable for moderate to high-load mechanical connections. Sold in a package of 10.

These button socket cap screws are used across a wide range of mechanical assembly applications including equipment panels, enclosures, brackets, and structural subassemblies where a flush or near-flush fastener head is preferred. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity, making them common in interior mechanical builds and light industrial environments. They are installed by maintenance technicians, millwrights, HVAC equipment assemblers, and general mechanical contractors working on trade equipment and machinery.
