What are Set-Up Wedges?
Set-up wedges are tapered steel wedges used to level, align, separate, and position workpieces during fabrication and machine setup. Their slim, shim-style profile lets you make small, repeatable height changes under parts without jacks or bulky fixtures. Our selection features USA-made, drop-forged carbon steel wedges from Ken Forging for dependable shop use.
Why use Set-Up Wedges in the shop?
- Make precise height adjustments with small taps for predictable changes
- Create or fine-tune gaps beneath parts for clamping and tacking
- Support work on planers, shapers, and milling machines during setup
- Slim tip reaches under low-clearance features where blocks won’t fit
- Forged steel durability stands up to repeated installs and strikes
Common applications
- Leveling machine components before fastening or welding
- Separating tightly fitted parts without prying on edges
- Aligning plates, frames, and weldments prior to tack welds
- Creating service gaps to remove pins, covers, or bushings
- Supporting heavy parts while positioning rigging hardware
How to choose Set-Up Wedges
- Lift needed: Match wedge length and taper to the total height change you need
- Thickness: Confirm the thick end can enter the available gap without force
- Surface & finish: Bare/painted surfaces respond differently; pick a finish that suits shop or outdoor use
- Single vs. opposing pair: One wedge for quick nudges; back-to-back wedges for finer, centered control
- Forged, USA-made: Choose drop-forged carbon steel (Ken Forging) for strength and repeatability
Use and safety tips
- Wear eye/hand protection; strike squarely with appropriate hammers
- Avoid side-loading; don’t lever on a wedge to hold weight
- Make small, even taps to adjust height; check level after each change
- Remove wedges and secure with permanent fasteners when alignment is set
- Inspect for wear, mushrooming, or cracks; dress damaged edges before reuse

Frequently Asked Questions about Set-Up Wedges
What do set-up wedges do?
They provide a simple, controlled way to raise or align a part by tapping a tapered steel wedge under it, allowing precise adjustments during machine and weld setups.
Where are set-up wedges used?
In machine shops and fab shops—on planers, shapers, mills, and fixtures—to level work, create shim gaps, and position components before clamping or welding.
How do I get finer adjustment?
Use two wedges back-to-back (tips opposed). Advancing one and retreating the other centers the movement and gives very fine control.
Can wedges replace permanent shims?
No. Wedges are for temporary setup and adjustment. Once aligned, replace wedges with the proper fasteners or shims for permanent support.
How do I avoid damage when striking?
Use light, square strikes with a suitable hammer; avoid side-blows. Check for mushrooming and dress edges as needed to keep contact surfaces flat.
What material are these wedges?
They are drop-forged carbon steel, USA-made by Ken Forging, selected for strength and durability in repeated shop use.
When should I use a single wedge vs. a pair?
Choose a single wedge for quick nudges under one edge; choose an opposing pair when you need centered lift, greater stability, or micro-adjustments.
Do you carry metric sizes?
These set-up wedges are offered in common inch sizes. Refer to the item cards for current size availability.
