Clamp (tool)

A fastening device applying inward pressure to hold objects securely.

Last updated

Clamps are tools used to temporarily position components for various tasks.[1] One-handed trigger clamps, also called squeeze clamps, are bar clamps with a pistol grip and spring-loaded trigger.[2] These clamps allow a user to position and engage the clamp with one hand while keeping the other hand free.[2]

Key facts and history

Trigger clamps have been available for years and are common in builders' workshops and trucks.[2] Unlike traditional bar clamps requiring two hands, a squeeze clamp closes by holding the grip and pumping the trigger.[2] The Bessey PowerGrip trigger provides up to 200 lb. of grip, then a screw handle can reach 1000 lb. of clamping force.[2] Jorgensen’s heavy-duty E-Z Hold Expandable Bar Clamps feature a sliding dovetail joint to join two clamps end-to-end.[2]

DeWALT trigger clamps range from a 4-1/2-inch 35-lb. model to a 50-inch 600-lb. model.[2] Miter clamps are small spring clamps with sharp points that pinch mitered trim for tight joints.[2] Band clamps use easy-sliding latches and a screw mechanism for jobs where rope or ratchet straps are improvised.[2] Other temporary clamp types include C-clamps, bar clamps, pipe clamps, and spring clamps.[1]

Surgical clamps include hemostatic clamps, bone clamps, and Gomco clamps.[3]

What the research sources say

Rob Wotzak’s article in Fine Homebuilding notes that one-handed trigger clamps are the go-to choice for home builders due to convenience, versatility, and powerful grip.[2] Wotzak states that Irwin Quick-Grip heavy-duty clamps range from a four-pack of 6-inch clamps for $20 to a 50-inch model for $45.[2] According to Wotzak, Jorgensen’s heavy-duty line comes in 12-inch, 24-inch, and 36-inch models for $25, $30, and $35 respectively.[2] Wotzak reports that Bessey PowerGrip sells for $50 for the 12-inch model and $60 for the 24-inch model.[2]

Wotzak explains that Pony Hand Clamp may be more convenient than a bulky trigger clamp for thin sheets or small parts.[2]
