Value Collection 403246BR Hex Head Cap Screw 5/8-11 X 4-1/2 in

Product Description

The VALUE COLLECTION 403246BR is a partially threaded hex head cap screw designed for general mechanical and structural fastening applications. It features a 5/8-11 UNC thread with a 4-1/2 inch length under head, manufactured from Grade 2 steel with a zinc-plated finish that provides basic corrosion resistance in light-duty environments. The partially threaded shank allows the smooth portion to bear shear loads and helps align mating components. This fastener is installed with a 15/16 inch hex key or wrench and is suitable for use by mechanics, millwrights, pipefitters, and general tradespeople working with bolted assemblies.

This cap screw is well suited for light structural, mechanical, and equipment assembly applications where standard UNC inch-series fasteners are specified. The zinc plating makes it appropriate for indoor or protected outdoor use where moderate corrosion resistance is acceptable. It is commonly used in equipment mounting, frame assembly, and general bolted connections across HVAC, plumbing, and mechanical trade applications where Grade 2 steel meets the load requirements.

Key Features

• 5/8-11 UNC thread form for compatibility with standard inch-series tapped holes and nuts
• Partially threaded shank allows smooth shank engagement for shear and alignment applications
• Grade 2 steel construction suitable for general-purpose, non-critical fastening
• Zinc-plated finish provides basic corrosion resistance in dry or light-moisture environments
• 15/16 inch hex drive size works with standard wrenches and sockets
• 4-1/2 inch length under head accommodates moderate material stack-ups

Compatibility

Designed for use with standard 5/8-11 UNC tapped holes, hex nuts, and heavy hex nuts in inch-series bolted assemblies across general mechanical and trade applications.

Installation Notes

Installation requires a 15/16 inch open-end, box, or socket wrench. Verify thread engagement depth meets applicable design or code requirements before torquing. Do not overtighten Grade 2 fasteners in soft or tapped-hole applications where thread stripping is a risk. Always de-energize and isolate equipment before replacing fasteners on live mechanical systems.
