Value Collection HCI30500275N-025BX Hex Bolt 1/2-13

Product Description

The VALUE COLLECTION HCI30500275N-025BX is a Grade A325 hex head bolt designed for structural and heavy-duty fastening applications. It features a 1/2-13 UNC thread size with a 2.75-inch length under the head and a partially threaded shank. Manufactured from uncoated steel to ASTM A325 standards, this bolt delivers the tensile strength required for steel-to-steel connections in structural assemblies. It weighs 0.261 pounds and is supplied individually. Trades working with structural steel, heavy equipment, or load-bearing framing rely on A325-grade fasteners where proof-load and tensile ratings matter.

This bolt is suited for structural steel connections, equipment mounting, and heavy framing applications where ASTM A325 compliance is specified. The partial threading allows the unthreaded shank to bear shear loads across the joint interface, a common requirement in bolted steel connections per AISC specifications. It is commonly installed by ironworkers, millwrights, and mechanical contractors in both commercial and industrial settings.

Key Features

• Grade A325 steel construction meets ASTM A325 structural bolt standard
• 1/2-13 UNC thread for broad compatibility with standard nuts and tapped holes
• 2.75-inch length under head accommodates typical structural stack-ups
• Partially threaded shank transfers shear loads through the joint
• Bright/uncoated finish — field coat or leave bare per project specification
• Sold individually with no minimum quantity beyond one unit

Compatibility

Designed for use with standard 1/2-13 UNC heavy hex nuts and hardened washers in structural steel bolted connections per ASTM A325 fastener requirements.

Installation Notes

Installation of A325 structural bolts should be performed by qualified ironworkers or mechanical contractors following AISC and RCSC bolt specification guidelines. Always snug-tighten the connection before applying final pretensioning using a calibrated torque wrench, turn-of-nut method, or tension-control tool as required by the project specification. Harden washers should be used under the turned element. Do not reuse A325 bolts that have been fully pretensioned.
