Interchangeable 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.
Key Features

Option: Larger Drive Size (SBR)
These versions are ideal when you need a larger drive square in a smaller ratchet body.
Option: Socket Lock Pin (SLP)
When you need additional security with impact sockets ensuring a socket stays on a wrench, the Socket Lock Pin series provides a solid solution. Engineered for strength and built for durability.
Option: Hold & Drive Ratchet (DH)
Aerospace assemblies sometimes use a special fastener to ensure there are no gaps between surfaces. Sturtevant Richmont creates these ratchets using our existing designs. Holes are precision drilled to ensure flawless use while maintaining structural integrity. Plus you get the benefit of placing this head at the end of many different Sturtevant Richmont torque wrenches. Like all of our heads, our ratchets maintain the common centerline.
