Value Collection D30145-51/2 Hex Cap Screw 5/8-11

Product Description

The VALUE COLLECTION D30145-51/2 is a partially threaded hex head cap screw designed for general industrial and mechanical fastening applications. It is manufactured from Grade 5 steel with a zinc-plated finish that provides basic corrosion resistance in standard service environments. The screw measures 5/8-11 thread size with a 5.5-inch length under head and conforms to ASME B18.2.1 dimensional standards. This fastener is a standard UNC thread type and is suited for structural and mechanical assemblies where Grade 5 tensile strength is specified. Maintenance technicians, millwrights, and general contractors commonly install this type of fastener.

This hex head cap screw is appropriate for use in residential and commercial construction, equipment fabrication, and industrial maintenance applications. The partial thread configuration is typical for through-bolt or clamping applications where a smooth shank is needed in the grip area. The 5/8-11 UNC thread is a widely used coarse-thread standard that mates with standard 5/8-11 nuts and tapped holes. This fastener ships in a minimum order quantity of 10 pieces, with a package quantity of 1.

Key Features

• Grade 5 steel construction for mid-range tensile strength in structural fastening
• Zinc-plated finish for basic corrosion resistance in dry and mildly humid environments
• Partially threaded shank for clamping and through-bolt applications
• 5/8-11 UNC coarse thread — widely compatible with standard hardware
• Conforms to ASME B18.2.1 dimensional standards for consistent fit and interchangeability

Compatibility

Designed as a standard ASME B18.2.1 hex head cap screw compatible with any application specifying a 5/8-11 UNC thread, 5.5-inch length under head, Grade 5 steel, partially threaded configuration.

Installation Notes

Installation is performed with a standard hex wrench or socket set sized for a 5/8-11 fastener. Always torque to the value specified by the equipment manufacturer or structural drawings for Grade 5 fasteners at this thread size. Power down or de-energize any equipment being serviced before installing or removing fasteners in mechanical assemblies. Do not use in applications requiring Grade 8 or higher tensile ratings without verifying suitability.
