Value Collection 2-H-100C-450 Hex Head Cap Screw 316 Ss

Product Description

The Value Collection 2-H-100C-450 is a partially threaded hex head cap screw manufactured from Grade 316 stainless steel with a bright, uncoated finish. It measures 1-8 thread size with a 4.5-inch length under the head, making it suitable for heavy-duty fastening applications where corrosion resistance and structural integrity are required. Grade 316 stainless steel offers superior resistance to chlorides and harsh chemical environments compared to standard 304-grade fasteners. This fastener is installed by mechanical contractors, pipefitters, marine tradespeople, and industrial maintenance technicians working in corrosive or high-moisture service environments.

This cap screw is appropriate for use in marine, chemical processing, food service, and outdoor industrial applications where exposure to saltwater, moisture, or corrosive agents is a concern. The inch-system threading and hex drive head make it compatible with standard SAE tooling. Partial threading allows for a stronger clamping force in through-bolted assemblies where the unthreaded shank bears the shear load. It is commonly used in flanged connections, equipment mounting, and structural assemblies requiring corrosion-resistant hardware.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in chloride and chemical environments
• Partially threaded shank improves shear strength in through-bolted applications
• Bright uncoated finish maintains dimensional accuracy and avoids coating thickness variation
• Inch-system thread size 1-8 compatible with standard SAE wrenches and sockets
• 4.5-inch length under head suits deep-reach or thick-material fastening scenarios

Compatibility

Designed as an OEM-style replacement or general-use fastener for inch-system assemblies requiring Grade 316 stainless steel hex head cap screws with 1-8 thread size and 4.5-inch length under head.

Installation Notes

This fastener is installed by qualified mechanical, structural, or marine tradespeople using standard SAE hex wrenches or impact sockets. De-energize and isolate any connected equipment before beginning fastener installation or replacement. Apply an appropriate anti-seize compound when threading stainless fasteners into stainless or aluminum mating threads to prevent galling. Follow applicable torque guidelines from the assembly manufacturer or relevant codes such as ASME B18.2.1 for inch fastener standards.
