Accurate measurement for depth, holes, and lengths Precisely measures depth gaps, hole sizes, and lengths with exceptional accuracy, so you can make reliable decisions on the job instead of guessing. Clear 1 mm scale provides repeatable readings and simplifies verification for quality work. Durable ForCR stainless steel construction Built from ForCR stainless steel for long service life and reliable performance. Construction designed to stand up to everyday and field use. Easy to read and easy to use contrast, 1 mm markings are straightforward to read at a glance, reducing measurement errors and saving time. Adjustable nut mechanism lets you set and lock the tightness to suit preference and task requirements, improving control and consistency. Why this tool matters Eliminates uncertainty when checking depths and hole sizes, reducing rework and material waste. Compact, simple design makes it fast to use for repeated checks and measurements in tight spaces. Practical applications Metalworking and machining: check hole depths and bore sizes during setup and inspection. Woodworking and carpentry: measure countersink depths, gap clearances, and mortise lengths. General maintenance and DIY: verify hinge clearances, fastener depths, and component fit before assembly. Key attributes at a glance Function: depth, gap, hole size, and length measurement Material: ForCR stainless steel Scale: 1 mm markings Adjustment: adjustable nut mechanism for tightening and locking Reliable, simple, and practical — a precision gauge for , field, and home projects.
