Value Collection 3TSSF95C008 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 3TSSF95C008 is a flat socket cap screw designed for flush or countersunk fastening applications where a low-profile head is required. It features a 5/16-18 UNC thread and an overall length of 0.5 inches. The 82-degree flat head seats cleanly into countersunk holes, and the 3/16-inch hex socket drive accepts a standard hex key. Constructed from 316 stainless steel, this fastener resists corrosion in wet, marine, and chemically aggressive environments, making it a dependable choice for trade and industrial installations that demand material integrity over time.

This screw is suited for use in plumbing, HVAC, pool and spa equipment mounting, marine hardware, and general industrial assemblies where stainless fasteners are specified. The UNC thread profile is compatible with standard inch-pattern tapped holes. Its flat head profile allows installation flush with or below the surrounding surface, which is useful in applications where protrusion is not acceptable or where mating components must seat flat against each other.

Key Features

• 5/16-18 UNC thread for compatibility with standard inch-pattern tapped holes
• 82-degree flat head for flush countersunk seating
• 3/16-inch hex socket drive for precise torque application with a hex key or Allen driver
• 316 stainless steel construction for superior corrosion resistance in wet and chemical environments
• Overall length of 0.5 inches suits shallow countersink and thin-panel applications

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 5/16-18 UNC countersunk fastener in 316 stainless steel.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the receiving hole is properly countersunk to 82 degrees before installation to achieve full head seating. De-energize and depressurize any system before fastener service or replacement. Apply appropriate anti-seize compound when fastening into dissimilar metals to prevent galvanic corrosion.
