Value Collection 011339PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 011339PR is a hex socket cap screw designed for applications requiring a strong, compact fastener with a recessed drive. Sized at 7/16-20 UNF with 1 inch of length under the head, this screw is fully threaded and driven by a 3/8-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. These screws are used in mechanical assemblies, machinery, and structural connections where a flush or low-profile head is required. Installation is performed by machinists, maintenance technicians, and millwrights working on industrial and commercial equipment.

This screw is suited for precision fastening tasks in both light and heavy industrial environments. The 7/16-20 UNF thread pitch is a fine thread, providing increased thread engagement and better resistance to loosening under vibration compared to coarse thread equivalents. Common applications include machine frames, jigs, fixtures, hydraulic components, and other assemblies where a strong internal-drive fastener is needed. Sold individually, with a minimum order quantity of 100 pieces.

Key Features

• 7/16-20 UNF fine thread for secure engagement and vibration resistance
• 1 inch length under head, fully threaded for maximum thread engagement
• 3/8-inch hex drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meeting ASME/ANSI B18.3 and ASTM A574 standards
• Black oxide finish for moderate corrosion resistance and low-glare appearance

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 7/16-20 UNF fully threaded fastener with a 1-inch length under head.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician using the appropriate 3/8-inch hex key or Allen wrench. Always verify thread compatibility with the mating tapped hole before installation. De-energize and lock out any equipment before replacing or installing fasteners in live machinery. Refer to applicable torque specifications from the equipment manufacturer or relevant ASME standards for proper clamp load.
