Value Collection 49096 Hex Head Bolt 3/4-10 2-1/2 in Grade B7

Product Description

The VALUE COLLECTION 49096 is a 3/4-10 hex head bolt with a 2-1/2 inch length under head, manufactured from alloy steel to ASTM A193 Grade B7 specifications. Grade B7 alloy steel fasteners are engineered for high-strength, high-temperature, and high-pressure applications where standard hardware-grade bolts are not adequate. The uncoated finish means these bolts are ready for use as-is or can accept field-applied coatings. Licensed plumbers, pipefitters, millwrights, and mechanical contractors commonly specify ASTM A193 B7 studs and bolts for pressure vessel, flange, and structural connections.

ASTM A193 Grade B7 hex head bolts are widely used in industrial piping systems, pressure vessel flanges, heat exchangers, and mechanical assemblies subject to elevated temperatures or high clamping loads. The 3/4-10 UNC thread standard is a common size across a broad range of flange classes and structural connection points in both commercial and industrial settings. This bolt ships in a package quantity of 10, making it practical for small repair jobs or single-flange work.

Key Features

• Alloy steel construction meets ASTM A193 Grade B7 material requirements for high-strength fastener service
• 3/4-10 UNC thread form provides wide compatibility with standard nuts and flanges
• 2-1/2 inch length under head suits typical flange bolt-up and structural connection applications
• Uncoated finish suitable for field coating or use in controlled environments
• Sold in a package of 10 to match common single-connection fastener quantities

Compatibility

Designed as an OEM-style replacement or maintenance stock fastener for industrial piping, pressure vessel, and mechanical assemblies requiring ASTM A193 Grade B7 alloy steel hex head bolts in the 3/4-10 UNC thread size.

Installation Notes

Installation should be performed by a qualified pipefitter, millwright, or licensed mechanic following applicable codes such as ASME B31.3 for process piping or the applicable flange specification. Depressurize and isolate the system before removing or replacing flange fasteners. Verify nut material compatibility with ASTM A193 B7 bolts, as mismatched hardware grades can cause improper clamping or thread damage. Do not use impact tools at final torque without a verified torque procedure from the equipment manufacturer or engineering specification.
