What is an inch L-gauge used for?

An inch L-gauge sizes SAE bolts from 1/4" to 1" and checks their thread count and length. It is a single card for the three questions a buyer asks about a loose bolt.

How do I measure a bolt's length on an inch L-gauge?

Lay the bolt along the ruler on the long leg of the inch L-gauge, starting under the head. The tip of the threads lines up with the length in inches.

Can an inch L-gauge carry my logo?

Yes, an inch L-gauge can be printed with your logo before it ships. We email a free digital proof, and production starts once you approve it.

How big is the inch L-gauge card?

The inch L-gauge card measures 10.5" L x 5" W x 1/16" thick. It slips into a toolbox lid, a counter drawer or a flat mailer.

What is the minimum order for the inch L-gauge?

The inch L-gauge has a minimum order of 100 pieces. Price breaks follow at 300, 500, 1000 and 5000 pieces.

Who orders a custom L-gauge for SAE bolts?

Farm and fleet stores, hardware stores and equipment dealers order a custom L-gauge for SAE bolts. It helps their parts desk match a sample bolt quickly during busy seasons.

Description

A custom inch L-gauge measures an SAE bolt's diameter, threads per inch and length on one card, so a customer at the parts counter gets the right replacement on the first try. Built for farm stores, hardware counters and maintenance shops, it sizes standard bolts from 1/4" to 1" and puts your logo in the toolbox.

The L shape fits sizing holes, thread pitch teeth and a 9" ruler on one flat piece. The pitch teeth read Unified National threads, so a tech can tell coarse from fine before forcing a nut. Farm and fleet stores hand it out at the parts desk, where customers bring in bolts from tractors, trailers and mowers. Contractors keep one in the truck for job site repairs, and the white stock plastic gives a dark logo plenty of contrast. At 10.5" by 5" and 1/16" thick, it slides into a toolbox lid or a direct mail envelope. Hardware stores keep one at the bolt aisle so customers can check a sample before buying a box. Because the sizing holes, pitch teeth and ruler are on one card, it replaces three separate checks with one tool. Equipment dealers add it to new-owner kits for tractors and mowers, and parts managers like that a customer can measure without help, which frees the counter during busy hours.

Pair it with the metric L-gauge so the counter covers both measuring systems with matching cards, which keeps the look consistent across your branches. For nuts, rivets and drill bits, the full range of promotional bolt gauges has a gauge for each job.
