Stop Guessing Which Nut or Bolt Size You’re Holding
Screw a fastener onto the matching gauge and identify the thread size in seconds. The 44-piece set covers both inch and metric threads in a portable organized case.
44 detachable gauges
23 inch + 21 metric sizes
Red metric / blue inch coding
Portable storage case
44 PiecesFull-size checker set
SAE + MetricTwo thread systems
Aluminum AlloyDurable lightweight gauges
DetachableTake one gauge to the job
Check the thread instead of guessing
Screw It On. Match the Fit. Read the Size.
Thread the nut or bolt onto a matching gauge by hand. A smooth, correct fit helps confirm the size so you can replace missing, damaged or rusted fasteners with more confidence.
Fast identification
Compare similar-looking threads in seconds instead of relying on diameter alone.
Useful for fixed hardware
The detachable design lets you carry a single gauge to a bolt, threaded hole or tight work area.
Great for mixed hardware bins
Sort loose nuts and bolts into labeled compartments after confirming the thread size.
Built for repeat shop and garage use
Clear Markings, Color Coding and a Case That Keeps Every Gauge in Place
Red gauges identify metric sizes and blue gauges identify inch sizes. Clear markings make each piece easier to read, while the fitted foam case gives every gauge a dedicated position.
Aluminum constructionLightweight metal gauges for regular use.
Uniform thread spacingDesigned for direct size verification.
Clear markingsRead the size directly on the gauge.
Portable caseCarry the full kit without loose pieces.
Three clear ways to read the size
Find the Marking on the Gauge, Foam Position or Lid Chart
Size information is repeated around the kit so you can confirm a gauge quickly while working.
Double-side etched gauge
Each detachable piece carries its own size marking for quick reference away from the case.
Printed foam position
The storage slot is labeled so the correct gauge returns to the correct place.
Lid reference chart
The case lid groups the included metric and inch sizes for an at-a-glance overview.
44-piece size coverage
23 Inch Sizes + 21 Metric Sizes in One Case

Made for quick comparisons
Especially Useful When Inch and Metric Threads Look Almost the Same
Similar diameters can hide different pitches. Testing the fastener directly against the gauge helps separate near-matching SAE and metric threads before you install the wrong replacement.
Check nuts
Use the male-thread end to identify a loose nut.
Check bolts
Use the matching female-thread gauge to verify a bolt or screw.
Check tight locations
Remove only the gauge you need instead of carrying the whole set into the work area.
