Value Collection -30604-43 Hex Head Cap Screw 316 Ss

Product Description

The VALUE COLLECTION -30604-43 is a partially threaded hex head cap screw designed for fastening applications that require corrosion-resistant hardware. Manufactured from Grade 316 stainless steel with a bright, uncoated finish, this fastener follows the Unified National Coarse (UNC) thread standard at a 1-8 thread size. The 3-1/2-inch length under the head suits assemblies where partial thread engagement is required for clamping without full thread exposure along the shank. Machinists, maintenance technicians, and tradespeople specify 316 stainless for environments exposed to moisture, chemicals, or salt air.

This cap screw is suited for use in wet or corrosive environments, including marine installations, chemical processing equipment, food-service infrastructure, and outdoor mechanical assemblies. The UNC thread form is the standard for inch-system fastener applications across a wide range of industrial and commercial uses. The hex head drive allows for wrench or socket installation in confined or high-torque situations. This SKU is sold individually; a minimum order quantity of 5 units applies per order.

Key Features

• Grade 316 stainless steel construction provides strong resistance to chloride and chemical corrosion
• Partially threaded shank allows precise clamping force control and reduces thread engagement along the grip length
• UNC thread standard ensures broad compatibility with standard inch-system nuts, tapped holes, and inserts
• Bright, uncoated finish maintains dimensional accuracy and is suitable for surfaces where coatings would interfere with fit
• Hex head drive accommodates standard wrenches and sockets for high-torque installation

Compatibility

Designed as a standard inch-system hex head cap screw for use with UNC-threaded nuts, threaded inserts, and tapped holes requiring a 1-8 thread size and 3-1/2-inch under-head length.

Installation Notes

Installation is performed with a standard open-end, box-end, or socket wrench sized for the hex head. Ensure the mating thread is clean and free of debris before installation. Do not mix stainless steel fasteners with dissimilar metals in applications prone to galvanic corrosion without appropriate isolation. Apply an appropriate anti-seize compound when installing 316 stainless fasteners in stainless tapped holes to prevent galling.
