Value Collection -30145-41/2 Hex Head Cap Screw 5/8-11 X 4 in

Product Description

The VALUE COLLECTION -30145-41/2 is a partially threaded hex head cap screw designed for general mechanical assembly and structural fastening applications. Manufactured from Grade 5 steel with a zinc-plated finish, this fastener measures 5/8-11 thread size with a 4-inch length under the head. The UNC thread standard and ASME B18.2.1 compliance make it a reliable choice for trade professionals working on equipment installation, structural connections, and mechanical fabrication. Licensed tradespeople across HVAC, plumbing, and general mechanical contracting keep these fasteners on hand for a wide range of bolted joint applications.

This hex head cap screw is suited for residential and commercial mechanical installations where a partially threaded, inch-series fastener is required. The 5/8-11 UNC thread pattern and Grade 5 steel construction make it appropriate for moderate-strength bolted connections in steel-to-steel and steel-to-plate assemblies. Sold in a package quantity of 25, it is well-suited for contractors and technicians who need a reliable stock of standard fasteners for ongoing service and installation work.

Key Features

• Grade 5 steel construction provides moderate tensile strength for bolted mechanical connections
• Zinc-plated finish offers basic corrosion resistance in dry and mildly humid environments
• Partially threaded shank allows for precise clamping force in bolted joint assemblies
• 5/8-11 UNC thread pattern conforms to ASME B18.2.1 dimensional standards
• 4-inch length under head accommodates thicker material stacks and structural members
• Package quantity of 25 supports ongoing service inventory for trade professionals

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 5/8-11 UNC threaded hole or nut conforming to ASME B18.2.1 specifications.

Installation Notes

Installation of hex head cap screws is typically performed by licensed mechanical, HVAC, or plumbing technicians using standard hand tools or impact wrenches sized for a 15/16-inch hex head. Always ensure mating threads are clean and free of debris before assembly. Follow applicable codes and equipment manufacturer torque guidelines for the specific bolted joint. Do not exceed the rated strength of Grade 5 fasteners by substituting them in applications requiring Grade 8 or metric high-strength hardware.
