Integrated Round Spring Clasp for Secure Retention
One of the most convenient features of these PTO locking pins is the attached round spring-wire clasp.
The retaining wire pivots around the pin and snaps over its end, helping keep the pin from sliding out of a compatible mounting hole.
This eliminates the need to handle a separate retaining clip during installation.
The clasp design makes these pins particularly useful for applications requiring periodic equipment adjustments or accessory removal.
Benefits of the round locking clasp include:
-
Quick installation and removal.
-
No separate cotter pin required.
-
Attached retainer helps prevent lost hardware.
-
Secure retention when properly engaged.
-
Convenient operation for routine maintenance.
Always confirm that the spring clasp is fully seated before operating the equipment.
Precision 1/4-Inch Diameter for Compatible Equipment
Each PTO locking pin features a nominal 1/4-inch shaft diameter, equivalent to approximately 6.35 mm.
This size is commonly used in smaller equipment connections, accessory brackets, and various mechanical fastening applications.
The smooth round shaft allows the pin to slide through appropriately sized holes while the spring clasp provides retention.
Before purchasing, measure the existing pin diameter and verify that the replacement matches the equipment manufacturer’s requirements.
A pin that is too small can introduce unwanted movement, while an oversized pin may not install correctly.
2-1/4-Inch Usable Length for Proper Fitment
Correct pin length is just as important as diameter.
These locking pins feature an advertised usable length of 2-1/4 inches (57 mm), with an overall length of approximately 2-3/4 inches (70 mm).
The usable length refers to the space between the underside of the pin head and the locked retaining clasp.
This distinction matters because the entire pin length is not available for securing equipment.
Always verify that the combined thickness of the connected components fits within the usable length while allowing the spring clasp to close completely.
Convenient Three-Pack for Maintenance and Repairs
Small fastening components have a remarkable ability to disappear exactly when you need them.
This three-pack provides replacement pins for multiple compatible applications or spare hardware for your garage, trailer toolbox, or equipment maintenance kit.
Having additional locking pins available can save time during routine maintenance, accessory changes, and equipment repairs.

Ideal Applications for Stainless Steel PTO Locking Pins
Utility Trailer Accessories
These locking pins can be useful for retaining compatible trailer accessory brackets, removable components, and other noncritical fastening points.
Their stainless steel construction makes them suitable for equipment that is regularly stored outdoors.
However, these 1/4-inch pins should not be substituted for load-rated trailer coupler pins, receiver hitch pins, or safety-chain hardware without explicit manufacturer approval.
Lawn and Garden Equipment
Lawn tractors, garden carts, and other outdoor equipment often use removable pins for accessory adjustments and attachments.
The integrated retaining clasp allows convenient installation without requiring separate cotter pins.
Agricultural and Farming Equipment
PTO-style retaining pins are commonly associated with agricultural machinery and implement accessories.
These stainless steel pins may be suitable for compatible equipment guards, brackets, and accessory connections.
They are not automatically suitable for every PTO shaft, driveline, or rotating component. Always follow the equipment manufacturer’s fastening requirements.
DIY Garage and Workshop Projects
The smooth shaft and integrated retaining clasp make these pins useful for compatible removable brackets, adjustable fixtures, and other workshop projects.
Their reusable design is convenient for applications requiring occasional disassembly.
Truck and Towing Accessories
Truck owners may find these pins useful for certain removable accessory mounts and non-load-bearing equipment connections.

PTO Locking Pin vs. Standard Hitch Pin
Although these fasteners are sometimes marketed as trailer hitch pins, PTO-style round locking pins and conventional receiver hitch pins serve different purposes.
| Feature | Stainless Steel PTO Locking Pin | Typical Receiver Hitch Pin |
|---|---|---|
| Diameter | 1/4 inch | Often 1/2 or 5/8 inch |
| Retention | Integrated spring clasp | Separate clip or lock |
| Material | Stainless steel | Varies |
| Primary use | Compatible equipment and accessory fastening | Securing hitch-mounted accessories |
| Load rating | Not specified | Depends on product |
| Quick removal | Yes | Yes |
| Interchangeable | No, unless specifically approved | No, unless specifically approved |
A standard trailer hitch receiver generally requires a larger, properly rated hitch pin.
Do not use these 1/4-inch PTO pins as replacements for 1/2-inch or 5/8-inch receiver hitch pins.
How to Measure a PTO Locking Pin Correctly
Selecting the correct pin dimensions helps prevent installation problems and unnecessary equipment movement.
The diameter is measured across the round shaft. The usable length is measured from underneath the pin head to the locked retaining clasp. The overall length measures the entire pin from end to end.
For this product, the usable length is 2-1/4 inches, not the full 2-3/4-inch overall length.
Easy Installation and Removal
Installing a PTO round shaft locking pin generally requires only a few steps:
-
Confirm that the pin matches the equipment’s required diameter and usable length.
-
Rotate the spring clasp away from the shaft.
-
Align the mounting holes in the compatible equipment components.
-
Insert the pin fully through the holes.
-
Rotate the retaining clasp over the pin end until securely engaged.
-
Verify that the clasp cannot accidentally slip free during normal operation.
Before removing the pin, make sure the equipment is stationary, supported, and free from loads that could cause connected components to shift.
