Value Collection 3TSSF95C400 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 3TSSF95C400 is a flat socket cap screw designed for fastening applications that require a flush or countersunk finish. Threaded 5/16-18 UNC with an overall length of 4 inches, it uses a 3/16-inch hex socket drive and features an 82-degree flat head profile. The screw is manufactured from 316 stainless steel, which provides strong resistance to corrosion in wet, marine, and chemical-exposure environments. It is used by plumbers, pipefitters, maintenance technicians, and industrial tradespeople wherever a recessed, low-profile fastener is required.

This screw is well-suited for use in plumbing fixtures, pump housings, marine hardware, food-processing equipment, and other assemblies exposed to moisture or corrosive media. The 316 stainless steel material grade offers greater chloride and pitting resistance compared to standard 304 stainless, making it a practical choice for coastal and chemical plant installations. It is sold individually with a minimum order quantity of 10 units.

Key Features

• 82-degree flat head seats flush in standard countersunk holes, eliminating protrusion
• 3/16-inch hex socket drive for secure torque transfer with a standard hex key or Allen driver
• 316 stainless steel construction resists corrosion in marine, chemical, and wet service environments
• 5/16-18 UNC thread standard ensures broad compatibility with inch-series tapped components
• 4-inch overall length suits deeper assemblies and through-bolt applications

Compatibility

Designed as an inch-series UNC fastener for use in any application requiring a 5/16-18 flat socket cap screw with an overall length of 4 inches and a countersunk 82-degree head profile.

Installation Notes

Installation requires a 3/16-inch hex key or Allen driver sized to the socket drive. The mating material must be drilled and countersunk to the correct 82-degree angle to achieve a proper flush seat. Power down or depressurize any system before fastener replacement or assembly work. Minimum order quantity is 10 units per order.
