Value Collection 49099 Hex Head Bolt 3/4-10 Alloy Steel

Product Description

The VALUE COLLECTION 49099 is a 3/4-10 hex head bolt manufactured from alloy steel to Grade B7 material specifications under ASTM A193. The bolt measures 3.5 inches in length under the head with a 3/4-10 UNC thread pattern. It carries an uncoated finish, which is standard for high-strength fastener applications where a coating would interfere with torque-tension relationships or where the installer will apply their own protective treatment. Licensed plumbers, pipefitters, structural mechanics, and maintenance professionals install these bolts in high-pressure piping flanges, pressure vessels, heat exchangers, and structural connections where elevated tensile strength is required.

This bolt is sized for industrial and commercial applications that demand compliance with ASTM A193 standards. Grade B7 alloy steel fasteners are commonly specified in flange assemblies operating under elevated temperature and pressure, including steam piping, process piping, and pressure vessel closures. The 3/4-10 UNC thread size is widely used in flanged connections across ASME B16.5 and similar piping standards. This listing is sold in a package quantity of 10.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 fastener standard for high-strength applications
• 3/4-10 UNC thread form provides broad compatibility with standard hex nuts and flanged connections
• 3.5-inch length under head suits typical flange bolt patterns in process and utility piping
• Uncoated finish maintains dimensional accuracy for precision torque-tension control
• Sold in packs of 10 to support job-site quantities without overstocking

Compatibility

Designed as an OEM-style replacement or new-installation fastener for 3/4-10 UNC threaded applications requiring ASTM A193 Grade B7 alloy steel bolts, including flanged piping assemblies and pressure-containing equipment.

Installation Notes

Installation of ASTM A193 Grade B7 bolts in pressure piping or pressure vessel flange applications is typically performed by licensed pipefitters or journeymen mechanics following ASME and applicable local codes. Always de-energize and depressurize the system fully before disassembling or assembling flanged joints. Use calibrated torque tooling and follow the flange manufacturer or engineering specification for the required torque sequence and value. Inspect threads for damage before installation and replace any bolt showing thread deformation or corrosion.
