Value Collection -30170-6 Hex Head Cap Screw 1-8x6 Grade 5

Product Description

The VALUE COLLECTION -30170-6 is a partially threaded hex head cap screw engineered for general industrial and mechanical fastening applications. Built from Grade 5 steel with a zinc-plated finish, this fastener delivers solid tensile strength and basic corrosion resistance suitable for a wide range of structural and assembly tasks. The screw measures 6 inches under the head with a 1-8 UNC thread size, making it well-suited for through-bolting or nut-and-washer assemblies where a partial thread shank is required for shear load performance. Tradespeople and maintenance technicians installing equipment frames, brackets, and mechanical assemblies will find this a dependable standard-duty fastener.

This hex head cap screw fits into typical mechanical, industrial, and light structural installations where inch-series UNC fasteners are specified. The partial thread design leaves a smooth shank section near the head, which resists shear stress and keeps mating components aligned. It is appropriate for use in HVAC equipment mounting, plumbing fixture framing, electrical panel support structures, and general maintenance work wherever a 1-8 coarse-thread fastener is called out by specification or matching hardware.

Key Features

• Grade 5 steel construction provides reliable tensile and yield strength for medium-duty fastening
• Zinc-plated finish offers basic corrosion and oxidation resistance for indoor and sheltered outdoor use
• Partially threaded shank improves shear load performance and component alignment
• 1-8 UNC thread standard ensures compatibility with standard inch-series nuts, washers, and tapped holes
• 6-inch length under head accommodates thicker assemblies and through-bolt configurations
• Sold in packs of 12, allowing stocking for repetitive installation tasks

Compatibility

Designed as a standard inch-series UNC replacement or stocking fastener for use wherever a 1-8 coarse-thread hex head cap screw is specified in mechanical, structural, or equipment assembly applications.

Installation Notes

Installation should be performed by a qualified technician or mechanic familiar with fastener torque requirements for Grade 5 hardware. Always de-energize and lock out equipment before replacing or installing structural fasteners on powered systems. Use a properly sized hex socket or open-end wrench to avoid rounding the head. Apply a flat washer and nut on the through-bolt end where required by the assembly specification.
