A compact workshop gauge for quickly identifying sizes of nuts, bolts and drill bits, promising clear, repeatable readings. Handy for mechanics and keen DIYers who value speed and organisation. Is the GIMYUAN Thread Checker the missing bit of kit for a neater toolbox?
⚡ At a Glance
- • Measurement Range: Identifies 19 imperial thread sizes and 15 metric thread sizes plus eight drill bit sizes
- • Best for: DIYers, mechanics and hobbyists who need quick thread identification in a busy workshop
- • Not ideal for: Users who require digital readouts or certified metrology equipment for precision calibration
A sturdy aluminium plate with laser-etched imperial and metric markings identifies 34 common thread sizes and includes eight drill bit gauges. Rounded corners, hanging holes and removable non-slip pads make for practical workshop mounting.
Fast, accurate identification – with 34 thread slots and 8 drill bit gauges
Laser-etched slots match 19 standard imperial sizes and 15 metric sizes, while eight drill bit gauges cover common bit diameters from 4mm up to 14mm plus two fractional sizes. Clear pitch and size markings on the surface let users line up nuts, bolts and bits for an immediate match.
Quickly determine thread and bit sizes without trial-and-error. Save time when sorting hardware or preparing repair jobs.
Robust workshop build – with aluminium board and stainless-steel screws
A lightweight aluminium plate forms the main body while screws use stainless steel for corrosion resistance; the solid back plate reaches up to 0.2 in / 5 mm thick. Non-slip pads attach to the rear and can be removed for wall mounting or more secure placement.
Durable construction withstands regular handling and workshop conditions. Stable gauge reduces wobble for more reliable size checks.
Neat organisation and accessibility – thanks to all-in-one mounting and hanging holes
All accessories are fastened to the aluminium plate so gauges remain organised, and rounded corners plus built-in hanging holes allow wall storage. Dual length scales (15 cm and 6 inches) run along the edges for quick visual measurement of bolt or bit length.
Keep gauges visible and within reach to cut down search time. Easy wall-hanging frees bench space and keeps the kit orderly.
