Product Information

About this item

• COMPLETE METAL & WOOD FASTENER SOLUTION – This premium 2-pack bundle covers every inch of your workshop. It includes the Wall-Mounted Thread Checker for identifying 31 SAE/Metric machine nuts and bolts, PLUS the Precision Drill Bit Gauge for sizing #4-#14 wood screws. Whether you are fixing an engine or building a cabinet, you have the right reference tool.
• MASTER THE ART OF PILOT HOLES (ALUMINUM CHART) – Stop splitting wood and stripping screws. The wood screw gauge features a laser-etched chart that instantly matches screws to the exact fractional-inch pilot hole needed. It distinguishes between Softwood vs. Hardwood and Tapered vs. Straight bits (e.g., tells you to use a 15/64" bit for a #14 screw in softwood), ensuring a professional finish every time.
• INSTANT NUT & BOLT IDENTIFICATION – The thread checker board is your go-to for mechanical fasteners. It features 15 Metric and 16 Standard (SAE) heavy-duty stainless steel gauges. Simply screw your mystery bolt into the wall-mounted board to verify size and pitch before heading to the hardware store.
• AEROSPACE ALUMINUM & STAINLESS STEEL – Built for a lifetime of use. The thread checker uses rust-resistant stainless steel inserts, while the drill gauge is machined from 4mm-thick 6061 Aerospace Aluminum. Both feature fade-proof, high-contrast markings that resist oil, grease, and wear better than cheap plastic charts.
• BUILT-IN RULERS & EASY MOUNTING – Efficiency is in the details. The aluminum gauge includes dual-scale rulers (15cm Metric & 6-inch Imperial) for checking screw lengths and bit diameters. Both tools feature pre-drilled holes, allowing you to mount them side-by-side on your wall or workbench for a professional, organized "sizing station."
