Value Collection D30170-5 Hex Head Cap Screw 1-8x5 in

Product Description

The VALUE COLLECTION D30170-5 is a partially threaded hex head cap screw intended for general industrial and mechanical fastening applications. It is manufactured from Grade 5 steel with a zinc-plated finish that provides basic corrosion resistance in interior and moderate-exposure environments. The screw measures 5 inches in length under the head with a 1-8 UNC thread size, conforming to ASME B18.2.1 dimensional standards. This fastener is suited for machinists, millwrights, maintenance technicians, and general contractors working on structural assemblies, machinery mounting, and equipment fabrication.

This cap screw is used in a wide range of industrial, commercial, and light structural applications where a standard inch-series coarse-thread fastener is required. The partial thread configuration allows the unthreaded shank to bear load in shear and provides a clean fit through clearance holes before engaging a threaded nut or tapped hole. It is a common replacement or stock fastener for equipment maintenance and fabrication shops.

Key Features

• Grade 5 steel construction for reliable tensile and shear strength in standard industrial applications
• Zinc-plated finish provides basic corrosion resistance for interior and sheltered environments
• Partially threaded shank allows shear load bearing and precise clamping
• 1-8 UNC coarse thread for broad compatibility with standard inch-series nuts and tapped holes
• Conforms to ASME B18.2.1 for dimensional consistency and interchangeability
• Hex head drive accepts standard hex wrenches and impact sockets

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1-8 UNC threaded nuts, inserts, and tapped holes conforming to ASME B18.2.1 specifications.

Installation Notes

Installation is performed using a standard hex wrench or impact driver with a properly sized socket. Clean and inspect mating threads before installation to prevent cross-threading or galling. Do not exceed the rated torque for Grade 5 fasteners of this diameter as specified in applicable engineering references or equipment service documentation. Follow applicable safety and mechanical codes for the specific assembly type.
