Frequently Asked Questions (FAQs)
1. What is the purpose of a shim?
The purpose of a shim is to fill small gaps or spaces between objects. It is a thin piece of material that can be tapered or wedged to support, adjust for better fit, provide a level surface, or act as a spacer.
2. What is the difference between a shim and a washer?
While shims and washers may have a similar appearance, they serve different functions. Washers are designed to take and spread loads, while shims are used to fill space and adjust for fit.
3. Are shims and spacers the same thing?
Shims and spacers are not the same. Shims are typically thin and used to fill small gaps, while spacers come in a wider range of thicknesses and can be used as sleeves, bushings, axles, or pins.
4. What are plastic shims used for?
Plastic shims are commonly used to level and adjust surfaces. They can be used for tasks like aligning kitchen cabinets, leveling toilets, spacing and aligning tiles, packing panels for storage, and for external cladding applications.
5. What can I use instead of shims?
Instead of shims, you can consider using EZ-Hang brackets for installing doors. They provide an easier and quicker method, reducing clean-up time compared to traditional shim usage.
6. Do you have to use shims?
Shims are necessary for adjusting the final fittings of windows, doors, cabinets, and more. They are commonly used to bridge gaps when installing trim, doors, windows, or cabinetry projects, and can also help level floors, tables, or chairs.
7. Do you screw through shims?
Once the door or window is plumb and level, you can secure it by driving a nail or screw through the shims and into the framing.
8. Are plastic shims better than wood?
Plastic shims have advantages over wood, such as requiring less shaping and being available in consistent shapes, thicknesses, and material properties. They are also stronger, more durable than wood, and lighter and cheaper than metal.
