Value Collection 3TSSF98C308 Flat Socket Cap Screw

Product Description

The VALUE COLLECTION 3TSSF98C308 is a flat socket cap screw designed for fastening applications that require a flush or countersunk head profile. It features an 82-degree flat head driven by a 5/16-inch hex key socket. The fastener is manufactured from 316 stainless steel, which provides strong resistance to corrosion and chemical exposure. Threaded to a 1/2-13 UNC specification and measuring 3.5 inches in length, this screw is suited for structural and mechanical assembly work in demanding environments. It is installed by electricians, plumbers, millwrights, and general trade professionals.

This flat socket cap screw is appropriate for use in wet, marine, chemical, or food-processing environments where 316 stainless steel is specified for its superior corrosion resistance over standard 304 grade. The countersunk 82-degree head allows the fastener to sit flush with or below the mating surface, making it a common choice for panel assemblies, brackets, flanges, and equipment enclosures where a smooth surface finish is required.

Key Features

• 82-degree flat head profile for flush countersunk installations
• 5/16-inch hex socket drive for secure torque transfer
• 316 stainless steel construction for corrosion and chemical resistance
• 1/2-13 UNC thread for compatibility with standard inch-series tapped holes
• 3.5-inch length suitable for moderate material stack thicknesses

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any application requiring a 1/2-13 UNC threaded fastener with an 82-degree countersunk head.

Installation Notes

A licensed mechanic, millwright, or trade professional should verify that the mating material is properly countersunk to an 82-degree included angle before installation. Use a 5/16-inch hex key or hex bit driver rated for the required torque. Ensure all fastener locations are clean and free of debris prior to driving. Consult applicable mechanical codes and equipment manufacturer specifications for torque requirements.
