Value Collection 581303PR Hex Socket Cap Screw 10-24 Unc

Product Description

The VALUE COLLECTION 581303PR is a hex socket cap screw designed for secure, high-strength fastening in mechanical assemblies, tooling fixtures, and industrial equipment. This screw features a 10-24 UNC thread, a 5-inch length under head, and a 5/32-inch hex drive. It is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and reduces light reflection on exposed fastener heads. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for load-bearing applications where dimensional and strength compliance is required. Machinists, maintenance technicians, and mechanical contractors are the typical installers.

This cap screw is used in residential and commercial mechanical installations, machine component assembly, and maintenance applications where a recessed hex drive is preferred for torque access in tight clearances. The partial threading along the shank provides shear resistance in applications where the fastener passes through an unthreaded clearance hole before engaging a tapped bore. It is well suited for fixture plates, machine frames, and equipment mounting tasks.

Key Features

• 10-24 UNC thread form for compatibility with standard tapped holes and nuts
• 5-inch length under head accommodates deep-stack assemblies or thick material sections
• 5/32-inch internal hex drive allows use with standard Allen keys and hex bit drivers
• Partially threaded shank provides shear strength through clearance holes
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish reduces surface reflection and offers mild corrosion protection

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped 10-24 UNC threaded application requiring a 5/32-inch hex drive.

Installation Notes

Install using a calibrated hex key or hex bit driver sized to 5/32 inches to avoid stripping the drive socket. De-energize and lock out any equipment before accessing fastener locations on powered machinery, per applicable OSHA lockout/tagout procedures. Do not exceed the rated mechanical engagement depth of the tapped hole, and verify thread engagement is sufficient to carry the intended load before torquing. Inspect mating threads for damage or contamination before installation.
