Value Collection HHCSI20620300-020BX Hex Head Bolt 5/8-11

Product Description

The VALUE COLLECTION HHCSI20620300-020BX is a 5/8-11 hex head bolt with a 3-inch length under head, manufactured from steel to ASTM A307 specifications. It features partial threading and a bright, uncoated finish, making it suitable for general structural and mechanical fastening applications. The bolt follows the Unified National Coarse (UNC) thread standard and conforms to Grade A307 requirements. This type of fastener is commonly installed by ironworkers, pipefitters, millwrights, and general contractors wherever a standard heavy-hex or hex-head bolt is specified in structural or mechanical assemblies.

This bolt is appropriate for a wide range of commercial and industrial applications where ASTM A307 Grade A fasteners are specified, including low-carbon steel structural connections, equipment mounting, and general-purpose bolted assemblies. The uncoated finish suits indoor applications or installations where additional corrosion protection will be applied separately. The partial threading design provides an unthreaded shank section that is useful in lap joints and connections requiring a bearing surface along the bolt shank.

Key Features

• 5/8-11 UNC thread size with partial threading for shank bearing surface
• 3-inch length measured under the head
• Steel construction meeting ASTM A307 Grade A307 requirements
• Bright, uncoated finish for clean dimensional tolerance out of the box
• Hex head drive style for standard wrench or impact tool installation

Compatibility

Designed as a standard ASTM A307 hex head bolt for use in general structural and mechanical bolted connections wherever a 5/8-11 UNC partially threaded fastener is specified.

Installation Notes

Installation should be performed by qualified tradespeople following applicable structural or mechanical codes. Torque to the project specification or engineer-of-record requirements, as this prompt does not include rated torque values for this grade. Use appropriate wrenches or impact tools sized for the hex head. Inspect threads for damage before assembly and ensure the mating nut and any washers match the 5/8-11 thread standard.
