Value Collection -30604-4X Hex Cap Screw 1/2-13 X 5 in 316 Ss

Product Description

The VALUE COLLECTION -30604-4X is a partially threaded hex head cap screw designed for demanding fastening applications where corrosion resistance is critical. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener features a 1/2-13 UNC thread size and a 5-inch length measured under the head. The partial threading provides a smooth shank section that improves shear strength and alignment in bolted joints. It is a standard inch-measurement fastener suited for use in corrosive or marine environments where carbon steel fasteners would fail prematurely.

This hex head cap screw is commonly used in plumbing, HVAC, pool equipment, and marine installations where exposure to moisture, chemicals, or saltwater is a concern. The 1/2-13 UNC thread pattern is widely compatible with standard hex nuts, washers, and tapped holes in structural and mechanical assemblies. Trades such as plumbers, HVAC mechanics, and pool service professionals regularly use Grade 316 stainless fasteners when code or application conditions require elevated corrosion resistance beyond standard 304 stainless. Minimum order quantity is 25 pieces.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in wet or chemical environments
• Partially threaded shank improves shear load handling and bolt alignment
• 1/2-13 UNC thread standard — compatible with common inch-series nuts and tapped components
• Bright, uncoated finish — no plating to crack, chip, or react with process fluids
• 5-inch length under head suits deeper structural connections and through-bolt applications

Compatibility

Designed for use with standard 1/2-13 UNC inch-series hex nuts, flat washers, and lock washers in mechanical and structural assemblies requiring corrosion-resistant fasteners.

Installation Notes

Installation should be performed by a qualified tradesperson following applicable mechanical or structural codes. Always ensure mating threads are clean and free of debris before assembly. Avoid mixing stainless steel fasteners with dissimilar metals in wet environments to minimize galvanic corrosion risk. Use a calibrated torque wrench to achieve proper clamp load — refer to the applicable engineering standard for 1/2-13 stainless steel torque values.
