Value Collection D30111 Hex Head Cap Screw 1/2-13 X 2-3/4 in

Product Description

The VALUE COLLECTION D30111 is a 1/2-13 x 2-3/4 inch hex head cap screw manufactured from Grade 5 steel with a zinc-plated finish. The fastener features partial threading and conforms to ASME B18.2.1 dimensional standards, making it suitable for general-purpose structural and mechanical fastening applications. The UNC (Unified National Coarse) thread form is the standard choice for most steel-to-steel and steel-to-cast assemblies. Tradespeople, maintenance technicians, and mechanical contractors reach for Grade 5 zinc-plated hex cap screws when a reliable, corrosion-resistant fastener is needed for moderate-load connections.

This hex cap screw is used across a broad range of commercial and industrial fastening scenarios, including equipment mounting, structural steel connections, HVAC curb and equipment anchoring, electrical enclosure assembly, and general mechanical maintenance. The partial thread configuration is well suited for clamping applications where the unthreaded shank provides a bearing surface between joined components. The zinc plating provides basic corrosion resistance appropriate for indoor and light outdoor use.

Key Features

• 1/2-13 UNC thread size with 2-3/4 inch length under head
• Grade 5 steel construction for moderate-to-high strength fastening
• Zinc-plated finish for basic corrosion protection
• Partial threading allows unthreaded shank to serve as a clamping or bearing surface
• Conforms to ASME B18.2.1 dimensional standards
• Standard hex head accepts common 3/4 inch wrenches and sockets

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw per ASME B18.2.1, compatible with any application calling for a Grade 5 zinc-plated partially threaded fastener in that thread size and length.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a properly sized wrench or socket. Always ensure the mating nut or tapped hole is clean and free of debris before threading. Do not exceed the rated torque for Grade 5 fasteners in the specified diameter, and consult applicable mechanical or structural codes for load-bearing connections. Zinc plating is not rated for immersion or high-humidity environments where a higher-grade coating would be required.
