Frequently Asked Questions

What is the difference between wood and plastic shims?

Wood shims compress easily for tight fits but can absorb moisture; plastic shims are waterproof, reusable, and ideal for permanent installations.

Are composite shims better for outdoor use?

Yes, composites like those from StockYourHome resist rot and weathering, outperforming wood in exposed conditions.

How do I choose the right thickness for leveling?

Start with the smallest shim and stack as needed; color-coded packs (e.g., 1/16” to 1/4”) simplify selection for precise adjustments.

Can shims be used for heavy machinery?

For industrial loads, select heavy-duty plastic or steel shims rated for high compression; always verify load specs for safety.

Are these shims reusable?

Plastic, composite, and steel varieties are highly reusable, while wood is often single-use but biodegradable.
