Indicators Stands & Magnetic Bases

Choose a magnetic base when you need quick repositioning on ferrous surfaces or work on multiple setups; pick a fixed stand for higher rigidity and repeatable measurements where mobility and mounting to a surface are unnecessary

Stability depends on base mass, contact area, clamping mechanism, and arm design; look for heavy cast bases or strong magnets, fine-adjustment arms or joints, and minimal play at pivot points to maximize accuracy

Most stands accept standard 8 mm or 3/8-inch indicator stems and V-block mounts; check the product's stated stem diameter and mounting hole size to ensure compatibility with your dial or test indicator

Magnetic bases provide strong holding force on flat ferrous surfaces but can mark or distort thin or finely finished pieces; use protective shims, large contact area bases, or non-magnetic clamping alternatives for delicate work

Keep moving joints clean and lightly lubricated, prevent chip or coolant ingress, periodically check fasteners for tightness, and store magnetic bases away from sensitive electronics and in a dry place to prevent rust

Basic stands and small magnetic bases are commonly available under $50, while more robust or precision models with fine adjustments typically range from about (price varies) to several hundred dollars depending on size and features

Holding force is best on flat, clean ferrous surfaces; some magnetic bases feature swivel or flexible feet to conform to slight curvature, but for highly irregular or non-ferrous surfaces you may need clamps or adapters
