Value Collection 011013PR Hex Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION 011013PR is a hex socket cap screw threaded to the 1-72 UNF standard, designed for precision fastening applications where small-diameter, fine-thread engagement is required. This screw measures 1/4 inch in length under the head and is fully threaded along that length, maximizing thread engagement in shallow or thin-material applications. Manufactured from alloy steel with a black oxide finish, it delivers solid mechanical strength along with basic corrosion resistance in controlled environments. The 1/16 inch hex drive requires a matching hex key or Allen driver for installation and removal. Machinists, assembly technicians, and maintenance professionals working on instruments, electronics, or precision mechanical assemblies are the typical installers.

This fastener is suited for light mechanical assemblies, instrument housings, optical equipment, and other applications where a 1-72 UNF thread is specified. The fully threaded shank and compact head profile make it a practical choice in tight clearance zones or tapped holes in metal substrates. Alloy steel construction with black oxide coating is appropriate for indoor or low-moisture environments where a clean appearance and moderate surface protection are acceptable. These screws are sold in multiples of 100 per order with a package quantity of one unit.

Key Features

• 1-72 UNF thread size for fine-pitch, high-engagement fastening in precision assemblies
• 1/4 inch length under head, fully threaded for maximum thread engagement
• Alloy steel construction meets ASME/ANSI B18.3 and ASTM A574 fastener standards
• Black oxide finish provides a clean appearance with basic corrosion resistance
• 1/16 inch hex socket drive for use with standard hex keys or Allen drivers
• Compact screw profile suited for tight clearance and shallow tapped-hole applications

Compatibility

Designed as a standard 1-72 UNF fully threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574, suitable for tapped holes requiring a 1-72 fine-thread fastener in metal or other rigid substrates.

Installation Notes

Installation requires a 1/16 inch hex key or Allen driver; use of an incorrect or worn driver risks stripping the socket. Ensure the receiving tapped hole is clean, properly threaded to the 1-72 UNF specification, and free of debris before driving the screw. Do not overtighten, as the small thread diameter limits torque capacity. Black oxide finish is not a substitute for plating or coating in wet or corrosive environments.
