The Jorgensen adjustable handscrew is crafted to ensure maximum strength and durability. Seasoned, straight-grain hard maple wood jaws marry with cold-drawn steel spindles and nuts with special double-lead threads. Together they create a handscrew clamp that holds tightly over broad areas, providing greater reach and a wider distribution of pressure. The angle between the jaws can be adjusted to fit the work, allowing them to hold odd spaces easily. The clamps are easy to apply and remove quickly and provide protection against the marring of finished surfaces. Traditional hardwood handles are designed for comfort. 5 Inch reach.
