Value Collection 10048CH2 Hex Head Cap Screw 1-8x3 Grade 2

Product Description

The VALUE COLLECTION 10048CH2 is a partially threaded hex head cap screw designed for general-purpose mechanical fastening applications. Manufactured from Grade 2 steel with a zinc-plated finish for basic corrosion resistance, this fastener measures 1-8 thread size with a 3-inch length under head and follows Unified National Coarse (UNC) thread standards. It meets ASME B18.2.1 and SAE J429 specifications, making it a code-compliant choice for structural and non-structural assemblies. Installation requires a 1-1/2-inch hex key or wrench. This screw is sold individually and is suitable for plumbers, electricians, HVAC technicians, and general contractors who need a reliable, standardized fastener for equipment mounting, framing, and mechanical connections.

This cap screw is suited for use in residential and light commercial trade applications where a partially threaded, inch-series UNC fastener is required. Common installation scenarios include equipment mounting, ductwork support hardware, pipe hanger assemblies, and general mechanical framing. The partial threading allows for clamping force across unthreaded shank sections, which is useful when joining two members with a nut on the far side. The zinc coating provides a baseline level of corrosion protection appropriate for dry or intermittently moist indoor environments.

Key Features

• Grade 2 steel construction meets SAE J429 and ASME B18.2.1 standards
• Partially threaded shank for effective clamping in through-bolt configurations
• UNC thread form for broad compatibility with standard inch-series nuts and tapped holes
• Zinc-plated finish provides basic corrosion resistance for indoor applications
• 1-1/2-inch hex drive for use with standard wrenches or sockets
• Sold as a single unit to match exact project quantity needs

Compatibility

Designed as a standard inch-series UNC hex head cap screw compatible with any application requiring a 1-8 thread size, 3-inch length under head, partially threaded fastener conforming to ASME B18.2.1 and SAE J429.

Installation Notes

This fastener is installed by licensed tradespeople and general mechanics using a standard 1-1/2-inch open-end, box-end, or socket wrench. Always ensure mating threads are clean and free of debris before installation. Do not overtighten, as Grade 2 steel has lower proof load ratings than Grade 5 or Grade 8 fasteners. Follow applicable mechanical and building codes for fastener selection in structural applications.
