Century Drill Tool Co Inc 98402 Metric Pitch Gauge

Product Description

The CENTURY DRILL TOOL CO INC 98402 is a metric pitch gauge designed to measure thread pitch on metric fasteners and fittings. The gauge covers a pitch range of 0.50 to 1.75 and supports both NPT and BSP thread forms, making it useful across a wide range of threaded pipe and fastener applications. Sold in a package of two gauges, it gives technicians a spare on hand for field or shop use. Accurate thread identification is a prerequisite for selecting correct fittings, taps, and dies, and this tool provides a fast, physical reference without requiring calipers or thread counters.

This pitch gauge is suited for plumbers, pipefitters, HVAC technicians, and maintenance professionals who regularly work with metric-threaded pipe fittings and hardware. It is particularly useful when identifying NPT or BSP thread pitch before selecting replacement nipples, couplings, or threaded adapters. The dual NPT and BSP coverage makes it appropriate for both domestic and imported equipment service work where thread standards may vary.

Key Features

• Covers pitch range of 0.50 to 1.75 for metric thread identification
• Compatible with both NPT and BSP thread forms
• Sold as a 2-pack, providing a backup gauge for field kits
• Compact form factor suited for tool pouches and service bags
• Physical leaf-style gauge provides immediate tactile confirmation of thread pitch

Compatibility

Designed for use with metric-threaded fasteners and pipe fittings using NPT or BSP thread standards across a 0.50 to 1.75 pitch range.

Installation Notes

No installation is required for this hand tool. Select the appropriate gauge leaf and test fit it against the thread being identified until a flush, no-gap engagement is achieved. Keep gauge leaves clean and free of debris to ensure accurate readings. Store the gauge away from moisture to prevent corrosion of the measuring surfaces.
