Value Collection 063133PS Flat Socket Cap Screw 3/8-16x2 316SS

Product Description

The VALUE COLLECTION 063133PS is a flat socket cap screw engineered for applications requiring a flush or countersunk fastener profile. Sized at 3/8-16 x 2 inches with full threading along its entire length, it is driven by a 7/32-inch hex socket. The 82-degree flat head seats cleanly into countersunk holes, eliminating protrusion above the mating surface. Constructed from 316 stainless steel, it offers strong resistance to corrosion in wet, chemical, and marine environments. Licensed tradespeople, millwrights, and maintenance technicians install these fasteners in systems where head clearance is critical and corrosion resistance is required.

This screw is suited for use in plumbing, HVAC equipment panels, pool and spa hardware, and marine or coastal installations where 316 stainless steel is specified for its superior chloride resistance compared to 304 grade. The fully threaded 2-inch length provides maximum thread engagement across the full grip range, making it a practical choice for thin-material assemblies or applications where a nut is used throughout the full shank. UNC thread form is standard in inch-based mechanical assemblies across commercial and residential trade work.

Key Features

• 316 stainless steel construction for superior corrosion resistance in wet and chloride-rich environments
• 82-degree flat head profile seats flush in standard countersunk holes
• 7/32-inch hex socket drive for precise torque application with standard Allen keys or socket bits
• Fully threaded 2-inch length maximizes thread engagement throughout the grip
• 3/8-16 UNC thread form compatible with standard inch-series nuts and tapped holes

Compatibility

Designed as an OEM-style replacement or stocking fastener for inch-series mechanical assemblies requiring a 3/8-16 UNC flat socket cap screw in 316 stainless steel.

Installation Notes

Installation is performed by mechanics, plumbers, HVAC technicians, and maintenance tradespeople using a 7/32-inch hex key or socket bit. De-energize and depressurize any system before fastener removal or installation. Apply an anti-seize compound approved for stainless steel fasteners to prevent galling during installation, as 316 stainless is susceptible to thread galling when driven dry under load. Verify countersink angle matches the 82-degree flat head geometry before seating to avoid fastener damage.
