Value Collection 49095 Hex Head Cap Screw 3/4-10 X 2-1/4 in Grade B7

Product Description

The VALUE COLLECTION 49095 is a hex head cap screw designed for high-strength bolting applications requiring dimensional consistency and material traceability. Manufactured from Grade B7 alloy steel and conforming to ASTM A193, this fastener is built for pressure vessels, flanges, valves, and structural connections where tensile strength is critical. The thread pattern is 3/4-10 UNC with a length under head of 2-1/4 inches. The uncoated finish means it ships bare steel, making it suitable for applications where a specific coating or plating will be applied in the field or where coating compatibility must be controlled.

This screw is used in industrial, mechanical, and process-piping assemblies that demand ASTM A193 compliance — a specification common in high-temperature and high-pressure bolting. Typical install scenarios include flange bolt-up on pressure piping, equipment base plate anchoring, and structural steel connections where Grade B7 material certification is required by engineering specification or inspection protocol. Licensed pipefitters, millwrights, and maintenance mechanics are the primary installers of this fastener type.

Key Features

• Grade B7 alloy steel construction meets ASTM A193 material specification
• 3/4-10 UNC thread form for standard inch-series bolting applications
• 2-1/4 inch length under head provides usable grip length for flanged and structural connections
• Uncoated finish allows field-applied coatings or direct use where bare steel is specified
• Sold in packages of 10, with a minimum order quantity of 1 package

Compatibility

Designed for use in ASTM A193 Grade B7 bolting applications including pressure vessel flanges, valve assemblies, and structural connections requiring 3/4-10 UNC inch-series fasteners.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or mechanical contractors working to applicable ASME, ASTM, or engineering specifications. Always de-energize, depressurize, and isolate the system before servicing any bolted connection. Use calibrated torque tooling when a specific torque value is called out by the engineering drawing or flange specification — do not apply torque values not specified by the engineering authority for the joint. Inspect threads for damage and apply compatible anti-seize or lubricant only when permitted by the fastener specification.
