Value Collection 49033 Hex Head Bolt 3/8-16 Alloy Steel B7

Product Description

The VALUE COLLECTION 49033 is a 3/8-16 hex head bolt manufactured from alloy steel to Grade B7 material specifications under ASTM A193. With a length under head of 1-1/4 inches and a Unified National Coarse (UNC) thread form, this fastener is built for high-strength bolting applications where elevated tensile strength and temperature resistance are required. The uncoated finish leaves the base alloy steel exposed, making it suitable for environments where a specific coating or plating will be applied by the installer. Sold in a package quantity of 50, this bolt is commonly installed by millwrights, pipefitters, and maintenance mechanics in industrial and process piping assemblies.

Grade B7 alloy steel bolts conforming to ASTM A193 are a standard choice in flanged pipe joints, pressure vessel assemblies, heat exchangers, and structural bolting where elevated-temperature or high-pressure service conditions are present. The 3/8-16 UNC thread size fits standard heavy hex nuts and flanged connections designed for that thread pitch. This fastener is used in both light industrial maintenance and heavy process industry settings where ASTM material traceability is specified by engineering or code.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 fastener standard for high-strength bolting
• 3/8-16 UNC thread for compatibility with standard nuts and tapped connections in that thread class
• 1-1/4 inch length under head suits typical flanged joint and structural connection depths
• Uncoated finish allows field application of plating, coating, or lubricant as required by spec
• Sold in a pack of 50, supporting job-site and maintenance stocking needs

Compatibility

Designed as a standard ASTM A193 Grade B7 hex head bolt for use with 3/8-16 UNC nuts and tapped flanges in industrial piping, pressure vessel, and structural bolting applications where this thread size and material grade are specified.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or mechanical technician following applicable ASME, ASTM, or plant engineering specifications. Isolate and depressurize any system before removing or installing fasteners in flanged or pressure-bearing joints. Use calibrated torque tooling appropriate for the bolt diameter and joint specification. Do not mix Grade B7 fasteners with lower-grade hardware in the same joint unless engineering has approved the substitution.
