Value Collection -30604-46 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION -30604-46 is a 1-8 UNC hex head cap screw measuring 5 inches in length under the head, manufactured from Grade 316 stainless steel with a bright uncoated finish. This partially threaded fastener is built for applications where corrosion resistance is critical, including marine, chemical, and outdoor environments where standard carbon steel fasteners would fail prematurely. The 316 alloy provides superior resistance to chlorides and saltwater compared to 304 stainless. Licensed tradespeople and maintenance technicians specify this screw when structural integrity and long-term corrosion performance are both required.

This cap screw suits a wide range of industrial, mechanical, and trade installations. Partially threaded shanks are preferred when clamping two materials together without thread engagement through the full grip length, which helps prevent galling and provides a cleaner bearing surface. Typical applications include equipment mounting, pipe support hangers, pump and motor assemblies, and structural connections in corrosive or wet environments. Sold individually with a minimum order quantity of one.

Key Features

• Grade 316 stainless steel construction for superior chloride and saltwater corrosion resistance
• Partially threaded shank for improved clamping force and reduced galling risk
• 1-8 UNC thread standard for compatibility with standard inch-series nuts and tapped holes
• 5-inch length under head suits thicker structural and mechanical assemblies
• Bright uncoated finish maintains dimensional accuracy and allows for visual inspection

Compatibility

Designed for use with standard 1-8 UNC inch-series nuts, washers, and tapped holes in corrosion-resistant fastener assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson familiar with stainless steel fastener handling. Stainless steel fasteners are prone to galling during installation — apply an appropriate anti-seize compound and use calibrated torque tools to avoid thread damage. Always de-energize, depressurize, or otherwise isolate equipment before replacing or installing fasteners in mechanical systems. Follow applicable ASME or facility-specific torque and fastener specifications for the assembly type.
