Sturtevant Richmont SDRF dovetail head

Interchangeable Fine-Tooth Square Drive Ratchet Head for Dovetail Torque Wrenches

Reversible ratchet head with SR dovetail design. Ideal when a socket is to be used and there is significant rotation of the fastener required to complete the tightening.

Sturtevant Richmont offers different ratchets to meet the needs of different industries. In addition to the normal industrial assembly tool ratchets we also offer "Hold and Drive" ratchets for aerospace.

Features

• 4.5 degrees of swing arc required to engage the next tooth
• Smooth operation
• SR dovetail connector with outstanding rigidity and wear resistance
• Easy to rebuild with our fine-tooth ratchet renewal kit
• Sealed compartment to protect the gear from debris
• Reverse lever on back of ratchet

The unique SR dovetail design used to join head and wrench provides an exceptionally strong connection and allows complete interchangeability. The SR system contributes to both operational flexibility and enhancing your return on investment!

To achieve constant torque values when changing heads, exact lever length must be maintained. Virtually all SR heads share a precise distance from end of wrench to center of fastener. This is referred to as a “Common Center Line” and is very difficult to maintain using the cut and weld construction method.

Interchangeable heads with the same centre line may be interchanged among themselves arbitrarily, without needing the torque wrench to be adjusted again.
