Also known as “safety” pins, the recessed button pin keeps operators from inadvertently releasing the locking mechanism.

Big Sky Precision™ broke the mold when we developed our proprietary recessed-button pin. The finish, appearance and functionality of this pin sets the standard for world-class, Made-in-USA quick-release pins. You will not find a higher quality pin at any price.

Initially, positive-locking pins were developed for applications where exact length was not critical. In fact, MIL-SPEC requirements still set grip length tolerances at +.020 inches. Enter the Adjustable Grip fastener. If you have an application where depths vary, or if you need to draw pieces together, the Adjustable Grip Pin might be your solution. Of course, if you just need a tighter tolerance on your grip length, we can help with that too.

Big Sky Precision™ manufactures adjustable grip fasteners in any handle style, diameter and length.

Push-me/Pull-you pins are the most elegant pins to use. Push the actuator to insert the pin — just like a single-acting pin. But, just pull on the ring (or T) to remove the pin uni-directionally — and it’s still positive locking!

Pins can be made with anodized aluminum handles (any color) or stainless. 4130, 17-4, 304, 7075, 6AL-4V... or any other alloy can be your shank material. The ingenious mechanism we use for double-acting pins keeps costs down.

Your customers will love you for specifying this pin.

Big Sky Precision™’s Spring Pull Pins can be manufactured to any desired length and width with an added quarter-turn feature making them easy to customize for your application. Pull the ring or knob to retract the spring-loaded tip to allow adjustments. Release the ring or knob to lock the Pull Pin tip into the desired hole location.

These pins can be made from most materials and provide a cost-saving opportunity when you need to implement a positive-locking solution.

What to lock your quick-release pin into? For precision applications, many times you’ll need a receiver built to the same rigorous standards as our pins. Big Sky Precision™ offers a wide array of close-tolerance receivers with many mounting options. As always, we’ll make a special one for you if our standards don’t quite match your needs.

Big Sky Precision™ also pioneered quick-release “receiver caps.” Field testing has shown that the most insidious problem with ball-type locking pins in outdoor applications is dust. That’s why we developed end caps with o-ring seals to keep your pin working in the harshest environments.

Protect your pin and your product!

Big Sky Precision™ offers a plethora of options for the end of your quick-release pin. We first show-cased our closed end pin, designed for harsh environments, in 1998. Options include pressed plugs, threaded ends and solid ends, where the hole for the spindle is simply not drilled all the way through.

Another popular end option is the bull-nose. Although Mil-Spec drawings from the 1940's detail a straight chamfer, our computerized machines make light work of a full radius at the end. This radius can greatly aid when the receiver location is awkwardly placed — the pin almost guides itself in since there is no edge to catch.

For situations that require preservation of finishes, our dentless™ delrin tip is the ticket. Developed to protect the mirror finish of our cleat receivers, dentless™ tips also reduce metal-to-metal galling during insertion.

Custom ends can easily be made to your specifications. Morse tapers, stepped, o-rings, snap rings... the Sky's the limit!

Big Sky Precision™ excels in building your quick-release application with the shank that meets your requirements. We’ve worked with countless materials, from the common to the exotic. As always, if you have a special requirement, we’re happy to quote that as well!
