Panel clamp holding finished wood panels under even pressure

Types of Clamps: The Complete Guide to Every Clamp Style (Plus Metal & Industrial Clamps)

From a $30 hold-down to a $12,000 pneumatic door clamp, there are dozens of types of clamps — and picking the wrong one costs you time, money, or a ruined workpiece. This guide covers the different types of clamps used in woodworking, metalworking, and production shops, including a full breakdown of the types of metal clamps you'll run into on a shop floor, with real machines and real prices from our own inventory.

Quick refresher: a clamp is a device that holds two or more objects firmly together under pressure, so they can't shift while you're cutting, drilling, welding, or gluing. There are dozens of specific designs, but they all break down into a few practical categories — let's go through them. (New to clamping tools in general?

Types of Clamps

Different Types of Clamps for Hand & Manual Work

These are the clamps most people picture first — hand-operated tools for everyday holding, gluing, and assembly:

  • C-clamp (G-clamp) — a C-shaped frame with a screw jaw; the classic general-purpose clamp for wood, metal, and quick fixes.
  • F-clamp — a sliding-jaw clamp with a wider throat than a C-clamp, good for larger panels and one-handed adjustment.
  • Bar clamp — a long bar with a fixed and sliding jaw, built for wide panel and frame glue-ups.
  • Pipe clamp — works like a bar clamp but uses a length of pipe, so you can extend the reach for larger workpieces.
  • Spring clamp — a scissor-action, spring-loaded clamp for fast, light-duty holding.
  • Quick-release (trigger) clamp — a one-handed clamp that tightens and releases with a squeeze of the trigger.
  • Hand-screw clamp — twin-screw wooden jaws that won't mark fine woodworking stock.
  • Corner clamp — sits inside a 90-degree joint to hold perfectly square corners for boxes and frames.
  • Strap (web) clamp — a ratcheting nylon strap for securing large or irregularly shaped frames while glue sets.

Types of Metal Clamps for Metalworking & Industrial Use

Metalworking and CNC production call for a different category of clamp — built for holding metal stock, workholding fixtures, and welding setups instead of wood. Here are real types of metal clamps from our own catalog:

Specialty & Task-Specific Clamps

A few more types worth knowing, even if they're built for one job only:

  • Toggle clamp — a lever-action clamp mounted to a jig or fixture for fast, repeated holding on production runs.
  • Bench clamp (vise) — a fixed clamp mounted to a workbench with a stationary and movable jaw, for sawing, drilling, or sanding.
  • Locking chain clamp — a chain-jawed locking clamp for gripping irregular shapes or smooth round stock like pipe.
  • Beam clamp — secures a beam or pipe to a support structure, common in steel fabrication and rigging.
  • Miter clamp — holds mitered corners together at the correct angle while adhesive sets, used for frames and trim.

How to Choose the Right Type of Clamp

Picking a style is only half the job for a wide bar or pipe clamp glue-up — see our parallel vs. pipe vs. panel clamp comparison for how they stack up head to head.

  • Match the clamp to the material. Wood, metal, and plastic all call for different jaw types — padded jaws for finished surfaces, hardened jaws for metal.
  • Match the clamp to the volume. Occasional glue-ups call for hand clamps; daily production of panels, doors, or drawers calls for a dedicated clamping machine.
  • Check the capacity and force rating. Confirm the clamp's maximum reach and holding force actually fit your largest workpiece.
  • Not sure which type you need? Call us at 800-698-1646 and we'll help you match the right clamp — hand tool or full machine — to your shop.

FAQ: Types of Clamps Explained

What are the different types of clamps?

The different types of clamps include C-clamps, F-clamps, bar and pipe clamps, spring clamps, quick-release clamps, hand-screw clamps, corner clamps, strap clamps, toggle clamps, bench clamps, and industrial pneumatic clamping machines — each suited to a different material, volume, and task.

What are the types of metal clamps?

Types of metal clamps include CNC hex and hold-down clamps for machining and workholding, pneumatic air clamps for router and production lines, welding ground and interlock clamps, and heavy-duty vacuum or suction clamps for positioning metal or panel stock.

What type of clamp is best for woodworking?

For occasional woodworking, bar clamps and hand-screw clamps cover most glue-ups. For daily production of panels, cabinet doors, or drawers, a dedicated pneumatic clamping machine clamps and squares work far faster and more consistently.

What type of clamp is best for metalworking?

Metalworking typically calls for CNC hex clamps or hold-down clamps for fixturing on a mill or router table, and dedicated welding ground/interlock clamps for safe welding setups.
