## Overview

The Grip Thread Pitch Gauge MM & SAE is a compact, heavy-duty steel tool designed to precisely measure drill bit sizes from 1/16" to 1/2" and identify thread pitches in both metric (0.25-5.5mm) and SAE (4-42 TPI) standards. Its dual-sided design with a metal divider allows quick switching between measurement systems, making it an essential, portable tool for professionals and DIYers aiming for perfect thread matching and fastener sizing.

## Description

Use to provide the correct size of a drill bit, or can be used to size a fastener to determine what bit should be used with it. Heavy duty gauge steel. Measures drill bits from 1/16" to 1/2".

Review: Great (once you figure it out!) - Very happy with this after some initial confusion. Never having used one, I assumed that one end is metric, the other "non-metric." Wrong!! Well, duh! Metric and SAE front-to-back, no left-to-right! You'll find a metal divider along the length of the tool that separates the two types. One side is imprinted V-US-AMER-NAT 4-42. The reverse is METRIC 60deg; they are separated by a divider down the middle. So, hold it facing one way, and metric gauges are on BOTH left and right. Flip it over and SAE (non-metric) are likewise on both left and right. (Didn't come with instructions that would have been helpful.) Once I figured this out, it's easy-peasy! [BTW, I used the term "non-metric" along with SAE. The package says SAE, while the tool is imprinted with V-US-AMER-NAT. Someone who knows more will have to explain if there's a difference between V-US-AMER-NAT and SAE, or if that's a distinction without a difference.] The SAE (non-metric) pitches are in TPI (threads per inch), and a 1/4"-20 bolt matched perfectly to the gauge labeled 20, and 3/8"-16 matched perfectly to 16. Metric thread pitch is by the distance in mm between threads in mm. That's how the gauges are labeled. I put it to use immediately on my telescope adapter rings to distinguish tiny metric M 1.0 from M 0.75. After struggling to eyeball thread pitches with calipers, this works like a charm. It has plenty of metric and SAE sizes but double check the range to make sure it includes yours. My packaging states: - SAE 4-42 - Metric 0.25-5.5mm - 60 degree thread profiles Thumb wheels loosen or tighten the constellation of sizes so you can swing the ones you need into view and stow the others. You could use it to measure tapped threads INSIDE a hole or bolt if the hole is large enough to insert the gauge; I measure about 6mm clearance for inserting in a hole. Others mentioned rusting. Like a lot of machine tools, it comes with a light coating of oil but will probably rust in wet environments over time, so care for it appropriately. Numbers are inscribed into the metal with a small (2.5mm tall), clear font; older eyes may need reading glasses or a magnifier to read them more easily, but there's no more room for anything larger. Some reviews criticize the labels as hard to read; I think it's good enough given the space constraints. A nice addition to my toolkit for $10!

### ⭐⭐⭐⭐ Good tool with a minor issue
*by J***E on December 9, 2024*

Overall, for the price, I think this is a great tool. The range of thread guages offered is more then sufficent for most any requirements, and the design is easy and convenient to use. It feels to be of good, quality/durability as well. That being said, it seems there may be a slight quality control issue as my thread guage did not include the 2.0mm pitch guage and instead had a duplicate 1.5mm pitch guage in its place. This isn't a huge issue as it's the only one missing and I can still identify a 2.0mm pitch based on how the adjacent 1.75mm and 2.5mm guages fit, but I thought it was worth noting.
