Value Collection 011051PR Hex Socket Cap Screw 5-40 Unc

Product Description

The VALUE COLLECTION 011051PR is a hex socket cap screw designed for precision fastening in mechanical, industrial, and fabrication applications. Threaded to the 5-40 UNC standard, it measures 3/4 inch in length under the head and is fully threaded from head to tip. The 3/32-inch hex drive accepts a standard Allen-style hex key. Manufactured from alloy steel with a black oxide finish, this screw delivers solid tensile strength and moderate corrosion resistance in controlled or indoor environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it a traceable, specification-grade fastener suitable for demanding assembly work.

This screw is commonly used in machine assemblies, tooling fixtures, instrument housings, and light mechanical equipment where a flush or low-profile cap head and positive hex-drive engagement are required. The 5-40 UNC thread designation is a fine, small-diameter thread frequently found in precision instruments, electronics enclosures, and light-duty mechanical assemblies. Installation is typically performed by machinists, maintenance technicians, or assembly workers. Sold in multiples of 100.

Key Features

• 5-40 UNC thread size with fully threaded shank for maximum grip along the entire fastener length
• 3/4-inch length under head suits shallow-to-moderate depth tapped holes
• 3/32-inch hex socket drive for precise torque application with a standard hex key
• Alloy steel construction provides high tensile strength for the fastener size class
• Black oxide finish offers mild corrosion resistance and reduces light reflection in sensitive assemblies
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards

Compatibility

Designed as a specification-grade socket cap screw for use in any tapped or threaded application requiring a 5-40 UNC thread pattern and a 3/32-inch hex drive.

Installation Notes

Installation is performed with a 3/32-inch hex key or Allen driver. Ensure the mating tapped hole is clean, properly dimensioned to 5-40 UNC tolerances, and free of debris before driving. Apply thread-locking compound only if specified by the assembly drawing. Do not exceed the rated drive engagement depth, as the small thread diameter is susceptible to stripping if overtorqued.
