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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eGrade B7 alloy steel construction for elevated tensile and yield strength\u003c\/li\u003e\n  \u003cli\u003eCertified to ASTM A193 fastener standard for high-temperature and high-pressure service\u003c\/li\u003e\n  \u003cli\u003e1\/4-20 UNC thread form in inch measurement system\u003c\/li\u003e\n  \u003cli\u003e3-inch length under head for consistent grip length in flanged and structural joints\u003c\/li\u003e\n  \u003cli\u003eUncoated finish eliminates coating thickness variability in precision assemblies\u003c\/li\u003e\n  \u003cli\u003ePack of 50 units per order for efficient stocking and job-site use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned 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.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation 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.
