springclamp

Springclamp is a clamping device that uses a spring to bias its jaws toward a closed, gripping position. In its common form, one jaw is fixed while the other is moved toward it by manual action, and an internal or external spring provides the clamping force when the jaws are at rest. Some designs add a locking mechanism to hold the jaws closed without continuous pressure.

Construction and variants

Most springclamps employ a coil spring or a leaf spring, with jaws made of steel, stainless steel, or durable plastic. The jaws may be coated or padded to prevent marring delicate surfaces. Sizes range from tiny micro clamps used in electronics to larger workshop clamps. Actuation methods vary, including pistol-grip, squeeze-trigger, or simple spring-loaded clips. Quick-release levers, detents, or locking tabs are common features on models intended for repeated quick applications.

Applications

Springclamps are used for rapid, temporary holds in woodworking, metalworking, electronics assembly, photography, and laboratory work. They are particularly valued for fast setup and easy repositioning when securing boards, components, cables, or samples during inspection, gluing, soldering, or routing.

Advantages and limitations

Key advantages include simplicity, low cost, and no power requirement. They provide fast actuation and are easy to reposition. Limitations include moderate clamping force compared with heavier-duty clamps, potential jaw marring if not properly padded, and limited suitability for high-precision or high-load tasks.

Maintenance and care

Keep springs clean and free of corrosion, avoid overextending joints, and inspect jaws for wear or damage. Replace worn or deformed clamps promptly to maintain effective gripping.
