Value Collection 581175PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 581175PR is a hex socket cap screw designed for precision fastening in mechanical assemblies, tooling, and equipment maintenance applications. It features a 5-40 UNC thread size, a 1-1/4 inch length under head, and a 3/32 inch hex drive. Constructed from alloy steel with a black oxide finish, this screw delivers solid tensile strength and corrosion resistance suitable for industrial environments. The partial threading profile allows for controlled clamp load in standard threaded holes. It is installed by mechanical technicians, machinists, and maintenance professionals working with machine components and structural assemblies.

This screw is suited for use in light machinery, precision equipment, and structural fastening applications where a compact hex socket drive is required. The 5-40 UNC thread is commonly found in small mechanical and electronic assemblies. The black oxide coating provides a low-reflectance, mildly corrosion-resistant surface appropriate for indoor industrial use. This fastener ships in a minimum order quantity of 100 pieces per order, with a package quantity of 1.

Key Features

• 5-40 UNC thread size for use in standard small-diameter threaded holes
• 1-1/4 inch length under head for adequate thread engagement in deeper assemblies
• 3/32 inch hex socket drive for use with standard Allen or hex key tooling
• Alloy steel construction provides high tensile strength for demanding mechanical applications
• Black oxide finish reduces surface reflectance and offers mild corrosion resistance
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style replacement or standard fastener for use in mechanical assemblies, tooling fixtures, and equipment requiring 5-40 UNC hex socket cap screws.

Installation Notes

Installation should be performed by qualified machinists or maintenance technicians using the appropriate 3/32 inch hex key or Allen wrench. De-energize all equipment and relieve any mechanical tension before removing or replacing fasteners in load-bearing assemblies. Do not exceed the designed clamp load for the thread size and material pairing. Follow applicable ASME fastener installation guidelines for torque sequencing in multi-fastener joints.
