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.
Scrolling down this page provides you with a good look at our ratchets as well as the ratchet renewal kits.
All of our ratchets maintain our common centerlines.

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.
|Part Number||Model Designation||Drive Size (in.)||Hole Size (in.)||Hex Key Size|
|853246||SDRT||3/8||5/32||1/8 or 3 mm|
|853364||SDRT||1/2||5/32||1/8 or 3 mm|
|853590||SDRT||1/4||9/64||1/8 or 3 mm|
|853619||SDRT||1/4||1/8||3/32 or 2mm|
|853656||SDRT||3/8||1/8||3/32 or 2mm|
All ratchets wear out with use. We have ratchet renewal kits that are quick and easy to install.
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.
|Part Number||Model Designation||Drive Size|
|853304||SDRT 1/4 SOC LOCK PIN||1/4 inch|
|853305||SDRT 3/8 SOC LOCK PIN||3/8 inch|
|853548||SDRT 1/2 SOC LOCK PIN||1/2 inch|
These interchangeable head ratchets provide more power in small places. You get the access of a smaller ratchet body with the power of a larger square drive.
|853752||SDRT 1/4" body with 3/8" Square Drive||250 in-lbs|
|853395||SDRT 3/8" body with 1/2" Square Drive||1250 in-lbs|
|809508||SDRT 1/2" body with 3/4" Square Drive||2500 in-lbs|
These are ideal when you need a larger drive square in a smaller ratchet body.
Sooner or later even the best tools wear out. We created the Ratchet Renewal Kit for those times when your ratchet doesn't quite work as smoothly as it once did.
Ratchet Renewal Kits range in size from 1/4 inch drive up to 3/4 inch drive. It is important to order the size that corresponds to the one you are replacing. Kit part numbers are assigned by spindle size. In addition to a new spindle, the kit includes a reversing pin, washer, retaining ring, spring, and ball.
IMPORTANT: When replacing any part of a ratchet, all parts of the ratchet renewal kit MUST be used. While the parts may look OK to the eye, don't be tempted to take the shortcut.
Tools required to install a new Ratchet Renewal Kit include:
