Value Collection 581264PR Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION 581264PR is a hex socket cap screw designed for precision fastening in mechanical assemblies, machine components, and industrial equipment. It features an 8-32 UNC thread size and a 3.25-inch length under head, with partial threading for positive clamping against a bearing surface. The 9/64-inch hex drive accepts a standard hex key or Allen wrench for installation in tight or recessed clearances. Made from alloy steel with a black oxide finish, it delivers solid tensile strength with moderate corrosion resistance. Machinists, maintenance technicians, and millwrights typically source and install this fastener.

This screw is suited for light-to-medium duty mechanical applications where a socket drive profile is required due to clearance constraints or torque control needs. It is commonly used in machine tool fixtures, equipment enclosures, jigs, and assemblies where a low-profile drive recess is preferred over a hex head or Phillips interface. The partial thread length allows it to draw two components together cleanly without thread interference in the grip area.

Key Features

• 8-32 UNC thread size for compatibility with standard unified coarse thread tapped holes
• 3.25-inch length under head with partial threading for proper clamping
• 9/64-inch hex socket drive for use with standard Allen or hex key wrenches
• Alloy steel construction for elevated tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as an OEM-style replacement or service fastener for machinery and equipment using 8-32 UNC tapped holes requiring a socket cap screw with 3.25-inch length under head.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 9/64-inch hex key. Confirm the mating threaded hole is clean and properly tapped to 8-32 UNC before seating the screw. Do not over-torque alloy socket cap screws in soft or thin material substrates. Apply thread-locking compound where vibration resistance is required, following the equipment manufacturer's guidelines.
