Value Collection 211183PR Flat Socket Cap Screw 5/16-24

Product Description

The VALUE COLLECTION 211183PR is a flat socket cap screw designed for precision fastening applications where a flush or countersunk finish is required. Manufactured from alloy steel with a black oxide finish, this 5/16-24 UNF screw measures 1 inch in overall length and is fully threaded. The 82-degree flat head seats cleanly into countersunk holes, and the 3/16-inch hex socket drive allows for installation with a standard Allen wrench or hex bit. This fastener is commonly installed by machinists, millwrights, electricians, and mechanical contractors working with steel assemblies and precision equipment.

This screw is suited for general industrial and mechanical assembly work where a low-profile, flush-mount fastener is needed. The fine 5/16-24 UNF thread pitch provides strong clamping force and resistance to loosening under vibration, making it appropriate for equipment panels, machinery housings, jigs, fixtures, and similar applications. It ships individually but carries a minimum order quantity of 100 units, making it practical for stocking in trade bins or service van inventory.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a clean, low-profile finish
• Fully threaded 1-inch overall length maximizes thread engagement in thinner material
• 5/16-24 UNF fine thread for strong clamping and vibration resistance
• 3/16-inch hex socket drive for use with standard Allen wrenches or hex bits
• Alloy steel construction with black oxide finish for corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or general-use fastener for assemblies requiring a 5/16-24 UNF flat socket cap screw conforming to ASME/ANSI B18.3 and ASTM F835 standards.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen bit driver. Ensure the mating countersink is machined to the correct 82-degree angle to achieve full head seating. Always verify thread engagement depth before final torque to avoid stripping in softer base materials. Power down or de-energize any equipment before fastener service per applicable safety procedures.
