Century Drill 92943 Metric Thread Restoring File 0.80-3.00mm 2pk

Product Description

The CENTURY DRILL TOOL CO INC 92943 is a metric thread restoring file designed to rehabilitate damaged external threads on screws, bolts, studs, pipe, and pipe fittings. It covers a metric pitch range of 0.80 mm to 3.00 mm, making it suitable for a wide variety of fastener and fitting sizes encountered in plumbing, mechanical, and general trade work. The file features an oxide coating that inhibits corrosion, extending service life in shop and field environments. Each package includes 2 files. Plumbers, pipefitters, HVAC technicians, and maintenance mechanics reach for this tool when threads are bent, rusted, or cross-threaded and full replacement is not practical.

This thread restoring file is used wherever metric-threaded fasteners and fittings need to be returned to serviceable condition. Common applications include salvaging pipe fittings with minor thread damage, cleaning up rusted bolt threads before reassembly, and correcting cross-threaded studs on mechanical equipment. It also functions as a pitch gauge, allowing the technician to identify unknown metric thread pitches in the 0.80 mm to 3.00 mm range without a separate gauge set. The 2-piece pack supports bench stock for busy shops or service vans.

Installation Notes

Thread restoring files are typically used by licensed plumbers, pipefitters, HVAC technicians, and mechanical maintenance trades. Before working on threaded connections that are part of a pressurized system, shut off and depressurize the line per applicable codes. Use light, consistent strokes along the thread profile to avoid removing excess material. Do not use this file to cut new threads — it is intended for restoration of existing damaged threads only.
