A screw assembly (1) for a clamping device (4) comprises: a screw (2; 2) with a thread (20) having a thread axis (A) and a handle (3; 3) having a thread section (311) constituting a nut, wherein the screw (2; 2) and the handle (3; 3) are fixed together as a screw-nut assembly, wherein at least one of the thread section (311) of the handle (3; 3) and the thread (20) of the screw (2; 2) is formed at least partially with a geometry varying along the thread axis (A) such that the screw (2, 2) and the handle (3, 3) are engaged by helicoidal wedging.

Provided is a tool that includes a handle assembly including a top portion and a bottom portion. The tool also includes a lock plate disposed between the top and bottom portions and having a deflectable arm having a free end biased towards the top portion, a fixed end opposite the free end, an inner edge, an outer edge, and a detent near the free end and the inner edge. The tool additionally includes a blade having first and second ends, an indent in a bottom surface of the blade near the first end for engaging the detent in a closed position, and a ramp on the bottom surface near the indent defining a reduced thickness portion of the blade that reduces in thickness from the indent towards an edge of the blade to reduce contact between the detent and the blade during rotation of the blade.

A universal handle attachment for C-clamps. The handle attachment includes a rigid body having a first side to engage a C-clamp, and a second side opposite to engage a rotation tool. In the first side, a first channel and a second channel which are perpendicular with one another each are configured to receive a T-bar of the C-clamp. A center space in the first side at the intersection of the first channel and the second channel is configured to receive a top end of the screw. Each channel includes clip spaces on both sides of the center, and clips situated in the clip spaces. The clips each have an opening to secure the T-bar within the channels.
