Embodiments of a multi-purpose utility clamp may include a component engagement member having a clamp head and a handle. A guide arm is operatively connected to the component engagement member at a first end of the guide arm. A first post is operatively connected to a second end of the guide arm to move linearly relative to the guide arm. A second post at an end of the support post is disposed generally perpendicular to the first post and has a first end connected to the first post and a second end, distal the first end, and the second end is disposed opposite the clamping head. The second post has a generally trapezoidal cross-sectional shape along a length thereof between the first end and the second end, and the second post is configured to be inserted into a channel having a corresponding trapezoidal shape and formed in an auxiliary component to be clamped to another component.

A spring clamp for assembly fixturing includes a retainer that limits a minimum distance between jaws of the spring clamp when the spring clamp is in a relaxed state.

Disclosed is a handle clamp for an exothermic mold. The clamp includes a pair of legs, each having a plurality of rods that are shaped to fit into engagement holes on sections of the mold. The rods of each leg engage with one section of the mold. Engagement brackets are rotatably disposed on one or more or the rods. The brackets each have a thumb bolt that can be extended toward a mold section connected with the clamp. When engaged with the mold section, the thumb bolt stabilizes the mold section on the handle. A detent mechanism is provided between the bracket and the leg of the handle. The detent mechanism releaseably holds the bracket in one of a selected plurality of rotational positions with respect to the rod. By selecting different rotational positions for the brackets, the handle can be configured to engage with different configurations of mold. The thumb bolts that are biased toward the mold section by a spring. The bolts include a key that can be aligned or misaligned with a key slot on the bracket. By aligning the key with the key with the key slot, the bolt can be moved toward or away from the mold section under the biasing force of the spring. By misaligning the key and key slot, the bolt can be locked into engagement with the mold section or else held in a disengaged position.

A trigger clamp includes a rail, a movable jaw configured to move along the rail, a handle fixed relative to the movable jaw, and a trigger movable relative to the handle, which when pulled towards the handle causes movement of the movable jaw along the rail. The handle comprises a trigger facing wall generally extending along a first plane, and a fin generally extending to a second plane, the second plane being closer to the trigger than the first plane. The trigger is shaped to be received to an interior of the fin at least when the trigger is squeezed by a hand of a user, such that an index finger of the user remains at the exterior of the fin. Methods of manufacturing and using similar trigger clamps are also disclosed.

A clamp mount and workpiece alignment apparatus is provided. Clamp including a workpiece alignment apparatus is provided. A method of clamping is provided. The clamp mount and workpiece alignment apparatus is used to mount to a support surface of a workpiece support and for positioning at least one workpiece relative to the clamp while the workpiece is supported on the support surface is provided. The apparatus includes a base, a base mount, a workpiece alignment guide, a clamp mount and an adjustable interface between the base and workpiece alignment guide.
