Torque / Clamping Force Chart

Speed Torq Handle™ Specifications

Drive screws on milling vises can vary from one manufacturer to another. The smaller the thread pitch, the greater the mechanical force. (clamping force) Therefore, vises tightened with our preset Speed Torq Handle™ will have different clamping forces across different vise brands. The Speed Torq Handle™ was designed to provide repeatability with clamping pressure. It will not provide the same clamping pressure across the different brands of vises. However, it will provide consistent clamping pressure on a specific vise, no matter who tightens the vise.
