Value Collection D30283 Hex Cap Screw 1/2-20 X 2 in Grade 5

Product Description

The VALUE COLLECTION D30283 is a hex head cap screw designed for secure mechanical fastening in a wide range of structural and equipment assembly applications. Sized at 1/2-20 (UNF thread) with a 2-inch length under head, this screw is manufactured from Grade 5 steel with a zinc-plated finish that provides corrosion resistance in typical indoor and light outdoor environments. The partially threaded shank allows for clamping force to be distributed across the unthreaded grip zone, making it well suited for applications where joint integrity under load is critical. This fastener conforms to ASME B18.2.1 dimensional standards. Installation is carried out by mechanical assemblers, maintenance technicians, and trade professionals working on equipment frames, brackets, and structural connections.

This fastener is appropriate for use in general industrial, mechanical, and trade equipment assembly where a 1/2-20 UNF thread and 2-inch under-head length are specified. Common applications include HVAC equipment mounting frames, electrical enclosure hardware, plumbing support structures, and general machinery assembly. The zinc-plated finish makes it suitable for dry or mildly humid interior environments. Minimum order quantity is 25 pieces.

Key Features

• 1/2-20 UNF thread for fine-thread engagement and vibration resistance
• 2-inch length under head for moderate grip-length applications
• Grade 5 steel construction meets standard medium-strength fastener requirements
• Zinc-plated finish provides basic corrosion protection in indoor environments
• Partially threaded shank preserves clamping integrity across the grip zone
• Conforms to ASME B18.2.1 dimensional standards

Compatibility

Designed as a standard 1/2-20 UNF hex head cap screw for use in any application calling for an ASME B18.2.1-compliant Grade 5 partially threaded fastener with a 2-inch under-head length.

Installation Notes

Install using a standard hex socket or open-end wrench sized for a 1/2-inch hex head cap screw. Ensure mating threads are clean and free of debris before installation. Torque to the value specified by the equipment manufacturer or applicable assembly drawing — do not estimate torque without a reference specification. Inspect the zinc-plated finish for damage before installation in any environment where corrosion protection is critical.
