Value Collection B7SN1000725CP Threaded Stud Nut 1-8 Steel B7

Product Description

The VALUE COLLECTION B7SN1000725CP is a fully threaded stud with nuts, manufactured from Grade B7 alloy steel in an uncoated finish. Each stud measures 7.25 inches in length and carries a 1-8 UNC thread size with a 7B class of fit, making it suitable for heavy-duty fastening applications that demand precision thread engagement and reliable clamping force. The uncoated finish indicates bare steel with no added plating or coating, which is common in industrial bolting applications where galvanic compatibility or field coating is handled separately. This package contains four studs and eight nuts, installed by millwrights, pipefitters, maintenance technicians, and general industrial tradespeople.

These Grade B7 threaded studs are used extensively in flanged pipe connections, pressure vessel assembly, industrial equipment mounting, and structural bolting where high tensile strength fasteners are required. Grade B7 material meets ASTM A193 standards for high-strength alloy steel bolting, making it a standard specification in oil, gas, petrochemical, and general industrial environments. The 7B class of fit provides the standard allowance for external threaded fasteners used with 7H or 7B internal threads in heavy mechanical and process piping assemblies.

Key Features

• Grade B7 alloy steel construction for high tensile strength and durability
• 1-8 UNC thread size with 7B class of fit for consistent thread engagement
• 7.25-inch fully threaded length accommodates varying flange and stack thicknesses
• Uncoated finish suitable for applications where post-installation coating or galvanic isolation is managed separately
• Package includes four studs and eight nuts for ready-to-install use

Compatibility

Designed as a standard Grade B7 fully threaded stud for industrial flanged connections, pressure vessel bolting, and heavy-duty mechanical assemblies requiring 1-8 UNC threaded fasteners with a 7B class of fit.

Installation Notes

Installation is typically performed by licensed pipefitters, millwrights, or qualified maintenance personnel following applicable ASME and ASTM bolting procedures. Always derate or de-energize systems and relieve pressure before removing or installing fasteners on pressurized assemblies. Thread engagement should be verified before torquing, and a suitable lubricant or anti-seize compound should be applied as required by the applicable bolting specification. Do not modify or cut studs without verifying thread integrity and minimum engagement requirements.
