Value Collection -30577-1 Hex Cap Screw 1/4-20 Grade 316

Product Description

The VALUE COLLECTION -30577-1 is a hex head cap screw designed for secure mechanical fastening in corrosion-sensitive environments. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener delivers strong resistance to moisture, salt, and chemical exposure. The screw uses a 1/4-20 UNC thread standard and measures 2-1/4 inches under the head with partial threading along the shank. Typical installers include plumbers, HVAC technicians, electricians, and general mechanical contractors who need reliable stainless fasteners for equipment mounting, panel assembly, or structural connections in wet or corrosive service conditions.

This fastener is suited for both residential and light commercial applications where corrosion resistance is a primary requirement. Common use cases include equipment enclosures, pool and spa hardware, marine-adjacent mechanical systems, and any installation where carbon steel fasteners would be prone to rust or galvanic degradation. The partial threading provides a smooth shank section that can improve clamping force and shear strength in through-bolted assemblies. This item is sold individually with a minimum order quantity of 100 pieces.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance compared to Grade 304
• 1/4-20 UNC thread for broad compatibility with standard inch-system hardware
• Partially threaded shank for improved clamping and shear load performance
• Bright, uncoated finish — no coating to chip, flake, or react with dissimilar metals
• Standard hex head accepts common wrenches and sockets without special tooling

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/4-20 UNC threaded hole or nut in equipment, enclosures, or structural assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation requires a standard hex wrench or socket sized for a 1/4-inch fastener head. Power down or de-energize any equipment before fastening into electrical enclosures or live panels. Avoid mixing stainless steel fasteners with carbon steel components in the same joint to minimize galvanic corrosion risk. Torque to the equipment manufacturer's specification for the joint material and fastener grade.
