Value Collection 49010 Hex Head Bolt 1/4-20 3in Grade B7 50pk

Product Description

The VALUE COLLECTION 49010 is a 1/4-20 hex head bolt designed for high-strength fastening applications where material integrity and dimensional consistency matter. Manufactured from Grade B7 alloy steel and certified to ASTM A193, this bolt is built for use in high-temperature and high-pressure environments common in industrial and mechanical assemblies. The 3-inch length under head and UNC thread form make it a straightforward fit for standard inch-system applications. The uncoated finish means no coating variability to account for in critical torque calculations. Sold in a pack of 50, this bolt is appropriate for both small-batch repairs and repeat production use.

This bolt is suited for use in flanged connections, pressure vessel assemblies, piping systems, and structural mechanical joints where ASTM A193 compliance is required. The 1/4-20 UNC thread is a widely used fastener standard across HVAC equipment frames, pump housings, valve bodies, and related trade hardware. Installers working under ASME or ASTM-specified joint requirements will find this bolt meets the common Grade B7 material specification for those standards.

Key Features

• Grade B7 alloy steel construction for elevated tensile and yield strength
• Certified to ASTM A193 fastener standard for high-temperature and high-pressure service
• 1/4-20 UNC thread form in inch measurement system
• 3-inch length under head for consistent grip length in flanged and structural joints
• Uncoated finish eliminates coating thickness variability in precision assemblies
• Pack of 50 units per order for efficient stocking and job-site use

Compatibility

Designed as a standard 1/4-20 UNC hex head bolt for use in any inch-system application requiring ASTM A193 Grade B7 alloy steel fasteners, including flanged pipe joints, equipment mounting, and pressure-rated mechanical assemblies.

Installation Notes

Installation should be performed by a qualified mechanic or pipefitter familiar with ASTM A193 torque and joint requirements. Always de-energize or depressurize the system before servicing any bolted connection. Use appropriate hex wrenches or socket drives sized for 1/4-inch hex head fasteners. Do not substitute Grade B7 bolts in assemblies specifying a different ASTM grade without engineering review.
