Value Collection 33591 Hex Socket Cap Screw 10-24 Unc

Product Description

The VALUE COLLECTION 33591 is a hex socket cap screw designed for secure fastening in mechanical assemblies, maintenance applications, and equipment fabrication. Sized at 10-24 UNC thread with a 5/8 inch length under the head, this screw is fully threaded for maximum thread engagement across the fastened joint. Drive engagement is achieved through a 5/32 inch hex socket, which accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide coating, the fastener offers improved corrosion resistance and reduced surface galling compared to plain steel. Licensed tradespeople, machinists, and maintenance technicians regularly specify this fastener type in both production and field repair work.

This screw is suited for general industrial and mechanical assembly applications requiring a low-profile socket-drive fastener. The 10-24 UNC thread is a coarse unified thread, common in light machinery, enclosures, brackets, pump housings, and HVAC equipment panels. The black oxide finish is appropriate for interior applications or assemblies where mild corrosion protection is acceptable. Full threading along the 5/8 inch shank length makes it well-suited for fastening into tapped holes or with a mating nut where full thread engagement is required.

Key Features

• 10-24 UNC fully threaded alloy steel construction for reliable thread engagement
• 5/32 inch hex socket drive for use with standard Allen keys or hex bit drivers
• 5/8 inch length under head accommodates typical light-gauge fastening applications
• Black oxide coating provides mild corrosion resistance and low-glare finish
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 10-24 UNC hex socket cap screw for use in any application requiring ASME/ANSI B18.3 compliant socket head cap screws in alloy steel with black oxide finish.

Installation Notes

Installation requires a 5/32 inch hex key or Allen driver; verify the drive tool seats fully before applying torque to avoid socket damage. Power down or de-energize any equipment before accessing fastened panels or assemblies. Inspect tapped holes for debris or thread damage prior to installation. Alloy steel fasteners with black oxide finish are not recommended for prolonged outdoor or high-moisture exposure without additional protective coatings.
