Value Collection MP63867 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION MP63867 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. Sized at 5/16-18 x 3/4 inches overall length with a Unified National Coarse (UNC) thread standard, this screw accepts a 3/8-inch hex socket drive and seats at an 82-degree flat head angle. It is manufactured from 18-8 stainless steel, offering solid corrosion resistance for both indoor and outdoor service environments. Maintenance technicians, millwrights, and general tradespeople use this fastener wherever a low-profile head is required to sit flush with or below a mating surface.

This flat socket cap screw is suited for light mechanical assemblies, equipment panels, brackets, and fixtures where a protruding head would interfere with clearance or appearance. The 5/16-18 UNC thread pitch makes it compatible with standard tapped holes of the same size. The 18-8 stainless steel construction resists mild chemical exposure and moisture, making it a practical choice for HVAC enclosures, pool equipment housings, plumbing access panels, and similar trade applications where corrosion resistance matters.

Key Features

• 82-degree flat head seats flush or countersunk in mating surfaces, eliminating head protrusion
• 3/8-inch hex socket drive for use with standard Allen keys or hex bit drivers
• 5/16-18 UNC thread for compatibility with standard tapped holes of that size
• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• 3/4-inch overall length suits shallow-to-medium depth fastening applications

Compatibility

Designed as a standard-dimension 5/16-18 UNC flat socket cap screw for use in any application requiring an 82-degree countersunk hex socket fastener in that thread size and length.

Installation Notes

Installation is performed with a 3/8-inch hex key or Allen bit driver. Ensure the mating hole is properly countersunk to 82 degrees to achieve a flush seat. Torque should be appropriate for the base material being fastened — consult applicable fastener torque tables for 5/16-18 stainless steel in your specific application. Minimum order quantity is 25 units per purchase.
