Value Collection 49034 Hex Head Bolt 3/8-16 Grade B7 50-pack

Product Description

The VALUE COLLECTION 49034 is a 3/8-16 hex head bolt manufactured from Grade B7 alloy steel to ASTM A193 specifications. It has a 1-1/2 inch length under head and an uncoated finish. ASTM A193 Grade B7 alloy steel is a high-strength fastener material commonly specified for pressure vessels, flanges, valves, and structural assemblies where elevated-temperature or high-stress service conditions apply. This bolt ships in a package quantity of 50 units, making it suited for project-quantity procurement. Licensed tradespeople in plumbing, mechanical, and industrial construction regularly specify this fastener grade when code or engineering drawings call out ASTM A193 compliance.

This bolt is used in applications requiring a proven high-strength fastener with a unified coarse (UNC) thread form. Typical install scenarios include bolting pipe flanges, securing pressure equipment, and assembling structural steel components in commercial and industrial settings. The uncoated finish is standard for applications where the service environment does not require corrosion protection coatings, or where a field-applied coating will be specified separately. Package quantity of 50 supports both single-joint and multi-joint work scopes without excess inventory.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 fastener standard for high-strength service
• 3/8-16 UNC thread provides broad tool and nut compatibility in inch-standard assemblies
• 1-1/2 inch length under head suits standard flange and structural connection depths
• Uncoated finish allows field coating or use in dry, controlled service environments
• Packaged in quantities of 50 to support project-scale procurement

Compatibility

Designed for use with 3/8-16 UNC hex nuts and washers in inch-standard fastener assemblies. Suitable for applications where ASTM A193 Grade B7 alloy steel fasteners are specified by engineering drawings or applicable mechanical and pressure-equipment codes.

Installation Notes

Installation should be performed by qualified mechanical, plumbing, or structural tradespeople in accordance with applicable codes and engineering specifications. De-energize, depressurize, and isolate any system before removing or installing fasteners on live equipment. Use properly calibrated torque tools and follow the torque values specified by the equipment manufacturer or the governing engineering document. Do not substitute a lower-grade fastener where ASTM A193 Grade B7 is specified.
