Which tool provides a 3/8 inch clearance between the bolt head and the anchor plate?

The taper bolt gauge is designed to measure the clearance between a bolt head and an anchor plate, specifically ensuring that the required space is met for proper function and installation. This tool has a specific design that accounts for the tapering effect of the bolt, which is important in applications where that taper influences the fitting or load distribution. The thickness of the gauge typically provides a reliable measure of the 3/8 inch clearance required, allowing users to check for adequate space effectively.

By using this tool, technicians can ensure that discrepancies in clearance are identified, which can prevent issues related to improper fastening or the potential for structural failures. It's particularly critical in engineering applications where bolts must fit precisely to maintain the integrity of the structure they support.

While the hammer gauge, clearance gauge, and anchor plate gauge may measure various aspects of fastening and fitting in construction or machinery, they do not specifically address the precise clearance needed between the bolt head and the anchor plate, making the taper bolt gauge the correct choice for this particular measurement requirement.
