Value Collection 015051PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 015051PR is a hex socket cap screw designed for secure, high-torque fastening in tight spaces where a standard hex head wrench cannot reach. It features a 5-40 UNC thread size, a 3/4-inch length under the head, and a fully threaded shank. The drive is a 3/32-inch internal hex socket, requiring an Allen key or hex driver for installation. Constructed from alloy steel with a black oxide finish, this screw delivers corrosion resistance and surface hardness suited to industrial, mechanical, and precision assembly applications. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This screw is used across a wide range of trade and industrial applications including HVAC equipment assembly, electrical enclosure hardware, pump and motor mounting, and general mechanical fabrication. The 5-40 UNC thread is a fine-pitch unified coarse designation commonly found in small-diameter fastener applications such as instrument panels, control boards, and light-duty mechanical assemblies. The black oxide alloy steel construction makes it suitable for indoor and light-duty environments where moderate corrosion resistance is required.

Key Features

• 5-40 UNC fully threaded shank for consistent thread engagement along the full length
• 3/32-inch internal hex socket drive for use with standard Allen keys or hex drivers
• 3/4-inch length under head provides adequate grip depth for typical panel and bracket fastening
• Alloy steel construction meets ASTM A574 for mechanical strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any application requiring a 5-40 UNC thread and a 3/32-inch hex drive in alloy steel with black oxide finish.

Installation Notes

Installation requires a 3/32-inch hex key or ball-end Allen driver. Ensure the mating threaded hole is clean and free of debris before driving. Do not over-torque small-diameter fasteners such as this 5-40 UNC screw, as the alloy steel shank can shear if torque limits are exceeded. Follow applicable mechanical assembly standards and equipment manufacturer guidelines for fastener torque specifications.
