Value Collection 581322PR Hex Socket Cap Screw 10-32 Unf

Product Description

The VALUE COLLECTION 581322PR is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies and equipment installations. The screw features a 10-32 UNF thread size, a 3-1/2 inch length under head, and a 5/32 inch hex drive. Constructed from alloy steel with a black oxide finish coating, it delivers strong clamping force while resisting surface corrosion in typical indoor service environments. Partial threading along the shank provides accurate shear-load distribution. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for use in precision mechanical and equipment-panel applications where dimensional accuracy and material strength are critical.

This screw is used in a wide range of trade and industrial applications including HVAC equipment panels, electrical enclosures, pump housings, and mechanical assemblies requiring a clean, recessed drive interface. The socket cap head allows installation in confined spaces where a hex wrench is accessible but a standard driver cannot be used. The black oxide alloy steel construction is appropriate for interior or protected service environments where fasteners are subjected to moderate mechanical loads.

Key Features

• 10-32 UNF thread for fine-pitch, secure engagement in tapped metal components
• 3-1/2 inch length under head accommodates deeper stack fastening applications
• 5/32 inch hex socket drive for installation with standard hex keys or socket drivers
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides surface corrosion resistance in protected environments
• Partially threaded shank for accurate shear-load distribution
• Conforms to ASME/ANSI B18.3 dimensional standard

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 10-32 UNF partially threaded alloy steel fastener with a 5/32 inch hex drive.

Installation Notes

Install using a calibrated hex key or socket driver matching the 5/32 inch drive specification. De-energize and lock out all equipment before servicing any panel or enclosure that requires fastener removal. Do not substitute a mismatched drive size, as this can strip the socket. Follow applicable mechanical and electrical codes, including NEC requirements where fasteners secure electrical enclosure covers.
