Thin Parallels, 4" Long, 11 Pairs, Premium

Thin Parallels, 4" Long, 11 Pairs, Premium - Main image
$63.97 $99.95 In stock

These 4" long thin parallels are great for the small 4" vises used on mini mills and bench mills because at a top size of 1" they can still fit in the vise. Smaller mill vises (under 6") are about 1" deep, meaning standard parallel sets have a bunch of parallels that can't be used. Custom made for LittleMachineShop.com, you can use ALL of these parallels.

This set of 1/8" thin parallels contains 9 pairs of parallels that step in 1/16" increments from 1/2" to 1". This gives you more sizes you can use in our small vises whose jaws are usually about 1" in height. No need to toss the taller sizes in most standard sets. The two pairs of shims, 9/64" and 5/32" high means that you can space things in 1/64" increments.

Parallel within 0.0002" on the top and bottom. The pairs are matched in height within 0.0002". Made of high-grade alloy steel hardened to 52 to 58 Rc. Comes in a wooden box

Eli ★★★★★

The 4-inch length pairs perfectly with my mini mill vise, and the precision ground finish is noticeably consistent across all 11 pairs. I’ve had no issues with binding or slipping during setups, which saves me time on every job.

Zoe ★★★★★

I was skeptical about how well these thin parallels would work in my 4" bench vise, but they hold securely and the 1" top size is perfect. The width is exactly what I needed for precise clamping without any wobble.

Penelope ★★★★★

Finally, a set of parallels that actually work in my 4" bench vise without hanging over the jaws. The 1" top size is the key — they slide in perfectly and stay level even on the mini mill.
