Bowmalloy 36006 Hex Head Cap Screw 1/4-20 X 1.5 in Grade 9

Product Description

The BOWMALLOY 36006 is a partially threaded hex head cap screw engineered for high-strength bolted connections in demanding trade and industrial applications. Built from Grade 9 alloy steel with a clear zinc chromate finish, this fastener delivers superior tensile strength and corrosion resistance over standard Grade 5 or Grade 8 hardware. The 1/4-20 thread size and 1.5-inch length under head make it a practical choice for structural assemblies, equipment mounting, and mechanical joints where fastener integrity is critical. Sold in packages of 100 units.

This fastener is suited for HVAC equipment assembly, electrical enclosure mounting, plumbing support brackets, and general mechanical fabrication where a high-strength inch-series hex cap screw is required. The partial threading pattern allows for precise clamping force in applications where a full-thread grip could compromise joint integrity. Grade 9 alloy steel construction makes it appropriate for vibration-prone environments common in mechanical systems installations.

Key Features

• Grade 9 alloy steel construction for higher tensile strength than standard Grade 5 or Grade 8 fasteners
• Clear zinc chromate finish provides corrosion resistance in typical indoor and sheltered outdoor environments
• Partially threaded shank allows positive clamping and shear resistance in structural joints
• 1/4-20 UNC thread form for broad compatibility with standard inch-series tapped holes and nuts
• Packaged in quantities of 100 for job-site and shop stock efficiency

Compatibility

Designed as a standard inch-series hex head cap screw compatible with any 1/4-20 UNC tapped hole or nut application requiring Grade 9 alloy steel fastener strength.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or trade technicians using a standard hex wrench or socket driver. Always verify that the mating tapped hole or nut meets or exceeds the Grade 9 strength rating to avoid fastener mismatch. De-energize and lock out all equipment before fastening or removing hardware on live mechanical or electrical assemblies. Follow applicable code requirements and manufacturer torque guidelines for the specific joint application.
