Retisee 28 Size 4'' x 20'' Bolt and Nut Identifier Gauge Nut Bolt Size and Thread Identifier Thread Pitch Gauge Standard Inch and Centimeter Ruler (Black,Stylish)

I find myself uncertain as to fastener style ( in. Vs mm) size and pitch. This tool will solve all those concerns without having to make a special trip to the Hardware Store to confirm the corect fasteners.

Very handy to have in the garage

Attractive accurate sturdy useable

I really like this product

Very happy with this product

Heavy duty, works well, would recommend

Very handy to check bolts and not sizes along with what type threads.

So far, it's super accurate. Two of the tapped holes had a little burr or two in them, but easily fixed. 4 stars for the burrs, but very nice gauge
