Value Collection -30604-33/4 Hex Cap Screw 1/2-13 316 Ss

Product Description

The VALUE COLLECTION -30604-33/4 is a partially threaded hex head cap screw designed for industrial and trade fastening applications. It is manufactured from Grade 316 stainless steel with a bright, uncoated finish, offering strong resistance to corrosion and chemical exposure in demanding environments. The fastener measures 1/2-13 thread size with a 3-3/4 inch length under head, following Unified National Coarse (UNC) thread standards. This screw is suited for use by mechanical contractors, plumbers, electricians, and maintenance professionals working in corrosive or wet environments such as HVAC equipment pads, plumbing fixtures, and pool or marine installations.

This hex head cap screw is commonly used in commercial and residential mechanical installations where corrosion resistance is a priority. Typical applications include securing equipment flanges, pipe supports, enclosure panels, and structural brackets in environments exposed to moisture, chemicals, or saltwater. Its 316 stainless steel construction makes it especially appropriate for coastal installations, chemical plants, food processing facilities, and pool equipment enclosures. The 1/2-13 UNC thread pattern ensures compatibility with standard inch-measurement threaded hardware.

Key Features

• Grade 316 stainless steel construction for superior corrosion and chemical resistance
• 1/2-13 UNC thread for compatibility with standard inch-system hardware
• Partially threaded shank provides clamping strength for structural fastening applications
• 3-3/4 inch length under head suits deep through-bolting and flange connections
• Bright, uncoated finish maintains dimensional accuracy and avoids coating interference in tight tolerances

Compatibility

Designed as a standard 1/2-13 UNC partially threaded hex head cap screw for use with any inch-system threaded nut, tapped hole, or coupling nut rated for 1/2-13 thread engagement.

Installation Notes

Installation should be performed by a qualified mechanical, plumbing, or electrical tradesperson following applicable codes and equipment manufacturer torque guidelines. Always use the correct size wrench or socket to avoid rounding the hex head. When fastening stainless steel hardware, apply an anti-seize compound to the threads to prevent galling during tightening. De-energize and depressurize any system before removing or installing fasteners on live equipment.
