JoblikeBrez 76-Size Thread Checker with Metric, Standard, and Drill Bit Gauges

Metric and standard thread-checking slots make it easier to identify nuts and bolts by size and pitch. The JoblikeBrez combines those checks with drill bit gauges and rulers in one workshop reference.

Match a fastener to its corresponding slot to read its size. Laser-etched markings help make the size information easy to read as you sort hardware or select a replacement.

The checker is made from 6061 aluminum with an anodized finish. Hang it on a workshop wall using the mounting hole, or set it on its silicone feet while you work.

Worth noting

This checker brings together 28 metric and 28 standard nut and bolt thread sizes, plus 20 drill bit gauges. Metric thread sizes run from M2 x 0.4 to M24 x 3.0, standard sizes run from #2-56 to 1-8. The selection covers multiple pitches within several sizes, giving you a clear reference when a fastener looks familiar but its exact thread is uncertain.

The manufacturer describes the checker as CNC-machined to meet the Go & No-Go Class 2B ANSI standard for internal and external threads. A 15 cm ruler and a 6-inch ruler are provided on both sides. Rather than keeping separate thread, drill-bit, and measuring references at hand, this design combines those functions in a single piece of shop equipment.

Who it’s for

This tool suits home garages, repair benches, and workshops where loose nuts and bolts need to be identified before a project or replacement. It is especially useful when hardware has been removed from a machine, fixture, or assembly and the size and pitch are no longer obvious. Its labeled slots offer a direct way to compare a part with the listed thread sizes instead of relying on visual estimates alone.

Buyers often highlight the straightforward identification process and the solid aluminum construction. Their feedback also points to the convenience of keeping common thread sizes together in one accessible workshop tool.

Best use cases

Use the checker when organizing mixed hardware, identifying a bolt before finding a matching nut, or confirming a thread size for a repair. For example, after removing a fastener from a bracket, match it to the corresponding slot to identify its size and pitch before choosing replacement hardware. The drill bit gauges add another reference point when sorting bits, while the rulers provide inch and metric measurements at the bench.

The wall-mounting hole keeps the gauge available in a fixed workshop spot. If you prefer it on the bench, the four silicone feet help keep it in place and protect the surface from scratches, according to the manufacturer.

Questions before you buy

What thread sizes does the checker cover? It has 28 metric sizes, from M2 x 0.4 to M24 x 3.0, and 28 standard sizes, from #2-56 to 1-8. Several sizes have more than one listed pitch, so use the matching slot to identify the fastener.

Can it check drill bits as well as fasteners? Yes. The checker includes 20 drill bit gauges, in addition to its nut and bolt thread slots.

How can it be positioned in a workshop? Hang it by its mounting hole or place it on a work surface using the four silicone feet. The rulers on both sides provide 15 cm and 6-inch measurements.

When it makes sense

Choose this JoblikeBrez checker when you want a single, easy-to-reference tool for identifying a broad selection of metric and standard threads, checking drill bits, and taking quick measurements at the bench. Its labeled slots, wall-mounting option, and combined ruler functions make it a practical fit for keeping hardware identification organized during repairs and workshop projects.
