 Hold and Drive Ratchets

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.

Socket Lock Pin

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

Small Ratchet Body With  Larger Drive Size

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. 

Part Number Model Designation
853752 SDRT 1/4 with 3/8 Square Drive
853395 SDRT 3/8 with 1/2 Square Drive
809508 SDRT 1/2 with 3/4 Square Drive

 These are ideal when you need a larger drive square in a smaller ratchet body.

 

Ratchet Renewal Kit

Ratchet Renewal KitSooner 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:

  • Snap ring pliers
  • Small flat head screwdriver
  • Tweezers
  • Molybdenum Disulfide
  • Vice or stand
