Value Collection 015049PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 015049PR is a hex socket cap screw designed for precision fastening in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 5-40 UNC thread size with 5/8 inch length under head and is fully threaded from head to tip. The 3/32 inch hex drive socket accepts a standard hex key or Allen wrench. Constructed from alloy steel with a black oxide finish, this screw offers strength and corrosion resistance suited to demanding service environments. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it appropriate for applications where dimensional and mechanical compliance matters.

This socket cap screw is used in a wide range of mechanical, manufacturing, and maintenance applications. Common uses include machine assembly, jig and fixture construction, and equipment repair where a low-profile screw head with high clamping force is required. The black oxide coating reduces light reflection and provides mild corrosion protection in dry or lightly oiled environments. Machinists, maintenance technicians, and assemblers working on precision mechanical systems will find this screw a reliable choice for close-tolerance fastening tasks.

Key Features

• 5-40 UNC thread size, fully threaded from bearing surface to tip
• 5/8 inch length under head for adequate grip in standard material thicknesses
• 3/32 inch hex socket drive for use with standard hex keys
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides corrosion resistance in dry and lightly oiled service
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in applications requiring a 5-40 UNC threaded fastener with a 3/32 inch hex drive in alloy steel construction.

Installation Notes

Installation is performed with a 3/32 inch hex key or Allen wrench; ensure the drive tool is fully seated to avoid rounding the socket. Clean and inspect threaded holes before installation to confirm thread condition and proper engagement depth. Do not exceed the torque capacity of the alloy steel fastener or the base material. When installing in corrosion-sensitive assemblies, consider supplemental lubricant or thread-locking compound appropriate for the application.
