Value Collection 3TSSF98C100 Flat Socket Cap Screw 316 Ss

Product Description

The VALUE COLLECTION 3TSSF98C100 is a flat socket cap screw engineered for fastening applications that require a flush or countersunk finish. It features a 5/16-inch hex socket drive and an 82-degree flat head profile that seats cleanly into countersunk holes. Built from 316 stainless steel, it offers strong resistance to corrosion in wet, chemical, and marine environments. The thread size is 1/2-13 UNC, and overall length is 1 inch. This fastener is a standard choice for mechanical assemblies, structural connections, and equipment maintenance tasks performed by millwrights, pipefitters, and general maintenance technicians.

This screw is suited for use in industrial, commercial, and marine applications where a flush-mounting fastener is required. The 316 stainless steel material grade makes it appropriate for installations exposed to saltwater, chlorinated water, or caustic chemicals. Typical use cases include pump and valve assembly, pipe support attachment, equipment enclosure fabrication, and pool or waterpark equipment maintenance. The 1/2-13 UNC thread is widely used across standard inch-system mechanical assemblies.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a smooth surface finish
• 5/16-inch hex socket drive accepts standard Allen or hex key tools
• 316 stainless steel construction resists corrosion in marine, chemical, and wet environments
• 1/2-13 UNC thread for compatibility with standard inch-system tapped holes and nuts
• 1-inch overall length suits moderate-depth fastening applications

Compatibility

Designed as a standard inch-system flat socket cap screw for use in any application requiring a 1/2-13 UNC thread and an 82-degree countersunk head profile.

Installation Notes

Installation is performed using a 5/16-inch hex key or Allen driver. Ensure the mating countersink angle matches 82 degrees before installation to achieve proper seating and load distribution. Power down or depressurize any equipment before disassembling fastened assemblies. Apply an appropriate anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling.
