Value Collection -30604-17 Hex Head Cap Screw 3/4-10

Product Description

The VALUE COLLECTION -30604-17 is a 3/4-10 UNC hex head cap screw measuring 2-3/4 inches under the head, manufactured from Grade 316 stainless steel with a bright uncoated finish. This partially threaded fastener is suited for structural and mechanical assemblies where corrosion resistance is a primary requirement. Grade 316 stainless steel offers superior resistance to chlorides and harsh environments compared to Grade 304, making it a common choice in marine, chemical processing, plumbing, and outdoor industrial applications. Installers in the mechanical and construction trades specify this screw where fastener integrity must hold up against moisture, salt, and chemical exposure.

This fastener is used in a wide range of trade and industrial applications including HVAC equipment mounting, plumbing fixture installation, pool and spa equipment assemblies, and general mechanical construction where stainless fasteners are required by specification or environmental conditions. The partially threaded shank provides a grip zone that allows the fastener to clamp mating materials without thread engagement through the full joint stack, which is preferred in many structural bolted connections. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in wet and chemical environments
• 3/4-10 UNC thread size with 2-3/4 inch length under head
• Partially threaded shank provides a clean bearing surface for clamped joint assemblies
• Bright uncoated finish — no plating to crack, flake, or introduce galvanic incompatibility with stainless hardware
• Hex head drive for use with standard wrenches and impact tools
• Inch measurement system, UNC thread standard for broad compatibility with standard tapped holes and nuts

Compatibility

Designed for use in standard 3/4-10 UNC tapped holes or with 3/4-10 hex nuts and washers in bolted assemblies requiring Grade 316 stainless steel fasteners.

Installation Notes

Installation should be performed by a qualified mechanic, pipefitter, or equipment installer familiar with fastener torque requirements for the specific joint application. Always verify thread engagement depth and ensure mating materials are compatible with Grade 316 stainless to avoid galvanic corrosion. Use calibrated torque tools appropriate for 3/4-inch fasteners and follow applicable mechanical or structural codes for the installation environment. Do not mix stainless fasteners with carbon steel hardware in wet or submerged assemblies.
