Value Collection 581302PR Hex Socket Cap Screw 10-24 Unc

Product Description

The VALUE COLLECTION 581302PR is a hex socket cap screw designed for precision fastening applications requiring high tensile strength and a clean, recessed drive. Manufactured from alloy steel with a black oxide finish, this fastener measures 4.5 inches in length under the head and uses a 5/32-inch hex drive. The black oxide coating provides mild corrosion resistance and reduces light glare in close-tolerance assemblies. Partially threaded along the shank, it is suitable for clamped-joint applications where a bearing surface is required. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assembly work across industrial and trade applications.

This screw is used in general mechanical assemblies, machine frames, fixtures, and equipment enclosures where a socket-drive fastener is preferred over a hex-head bolt. The partially threaded design is common in situations where the unthreaded shank needs to pass through a clearance hole before engaging the threaded bore. It is used by machinists, millwrights, maintenance technicians, and mechanical contractors working on equipment installation and repair.

Key Features

• Thread size 10-24 UNC for compatibility with standard inch-series tapped holes
• 4.5-inch length under head with partial threading for clamped-joint fastening
• 5/32-inch hex socket drive for use with standard Allen wrenches or hex bits
• Alloy steel construction meets ASTM A574 for high tensile strength requirements
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Meets ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as an OEM-style and general-purpose replacement socket cap screw for standard 10-24 UNC tapped holes in mechanical assemblies and equipment requiring ASME/ANSI B18.3 compliant fasteners.

Installation Notes

Installation requires a 5/32-inch hex key or Allen-type driver; use of a calibrated torque wrench is recommended to avoid stripping the socket or over-stressing the thread engagement. Power down and de-energize any associated equipment before beginning fastener service. Follow applicable mechanical codes and equipment manufacturer torque guidance for the joint material and thread class in use.
