Why Precision Brand: Tighter thickness tolerance vs generic shim stock = more accurate alignment. Cold-rolled material maintains thickness consistency across the roll. Cutting: roll stock cut to size on-site with tin snips or shim cutter. Use 304/316 SS in wet + corrosive applications; brass for non-sparking + soft-mating; carbon steel for general workshop. Brand: Precision Brand. Companion: shims + shim stocks, feeler gauges, bearings, feeler gauge guide.

People Also Ask — Precision Brand Shim Stock
Q: What thickness tolerance does Precision Brand shim stock hold?
Precision Brand shim stock holds a tight thickness tolerance — typically around ±0.0025mm — and is cold-rolled so the thickness stays consistent along the roll. That's tighter than generic shim stock, which is why it's chosen for critical machine alignment and levelling where a few microns matter.
Q: How do I choose shim material — steel, stainless or brass?
Use carbon steel for general workshop shimming, 304 or 316 stainless in wet, corrosive, or food-grade environments, and brass where you need a soft, conformable, non-sparking shim or a soft mating face. Match the shim material to the surrounding components to avoid galvanic corrosion in damp conditions.
Q: How do I cut shim stock to size?
Roll and sheet shim stock is cut to size on-site with tin snips or a dedicated shim cutter. Cut slightly oversize, then deburr the edges so the shim seats perfectly flat — a raised burr adds unwanted thickness and stops the joint pulling up square.
Q: What are slotted (horseshoe) shims used for?
Slotted shims have an open U-slot so they slide in under a motor or pump foot around the hold-down bolt without fully removing it. That makes them the fast way to correct shaft alignment and set soft-foot during machine installation and maintenance.
Q: What's the benefit of colour-coded shim stock?
Colour-coded shim stock identifies each thickness by colour, so an operator can grab the right shim at a glance instead of measuring every sheet. On a production alignment line that speeds the job and cuts the risk of fitting the wrong thickness.
Q: What's the benefit of pre-cut sheet shims over cutting your own from a roll?
Pre-cut sheet shims come in 150mm x 150mm packs ready for direct use, saving the step of cutting and deburring your own shim from a roll — useful when you need a consistent, ready-to-fit shim on hand.
Q: When would I choose an imperial slotted shim set instead of metric?
Imperial slotted shims use US-spec sizing for alignment of SAE-dimensioned machinery and couplings, while the metric slotted shim sets suit shaft and flange alignment on metric equipment — match the set to the dimensioning standard of the machine you're working on.
Q: What's in a Precision Brand mixed-thickness shim assortment pack?
An assortment pack bundles a range of shim thicknesses in one workshop variety pack, so you're not buying individual rolls or sheets of each thickness separately.
Q: Why is Precision Brand shim stock cold-rolled?
Cold-rolling keeps the material's thickness consistent along the length of the roll, which is part of what gives Precision Brand its tight thickness tolerance for critical alignment work.
