Value Collection 49050 Hex Head Bolt 1/2-13 Alloy Steel B7

Product Description

The VALUE COLLECTION 49050 is a 1/2-13 hex head bolt manufactured from alloy steel to Grade B7 specifications under ASTM A193. It features a 1-1/4 inch length under head measured using standard inch-system conventions and is supplied in an uncoated finish. This bolt is engineered for high-strength structural and industrial fastening applications where tensile strength and material traceability are required. Licensed tradespeople, millwrights, pipefitters, and mechanical contractors typically install this hardware in bolted flange assemblies, pressure vessel connections, and structural steel joints. Each package contains 50 pieces at a minimum order of 1 package.

Grade B7 alloy steel studs and bolts per ASTM A193 are a standard specification in pressure piping, flanged connections, and high-temperature industrial assemblies. This bolt is suitable for use in both commercial and industrial settings where code-compliant, traceable fasteners are required. The UNC thread form (1/2-13) is a common coarse-thread standard widely used in heavy mechanical and structural applications across the trades.

Key Features

• Grade B7 alloy steel construction per ASTM A193 for high-strength, code-traceable performance
• 1/2-13 UNC thread — coarse-thread standard for broad compatibility with nuts and tapped components
• 1-1/4 inch length under head for precise fastener selection in flanged or structural joints
• Uncoated finish — suitable for applications where galvanic compatibility or post-installation coating is required
• Sold in a 50-piece package to support job-site and shop-stocking quantities

Compatibility

Designed as an ASTM A193 Grade B7 compliant hex head bolt for use with standard 1/2-13 UNC nuts and tapped fittings in industrial piping, flanged assemblies, and structural steel applications.

Installation Notes

Installation of high-strength fasteners in pressure piping or structural applications should be performed by qualified tradespeople in accordance with applicable ASME, AISC, or facility engineering specifications. De-energize, depressurize, and isolate any system before servicing bolted connections. Use calibrated torque tools and follow the applicable torque sequence for flanged joints. Do not mix Grade B7 fasteners with incompatible nut grades or materials without verifying the joint design specification.
