Big Sky Precision is a full-service manufacturing plant offering state-of-the-art computerized machinings, engineering and design services

We don’t publish a price sheet: Big Sky Precision is a custom manufacturer and not a stocking distributor. For most pins, you'll find our pricing very competitive. In fact, new customers are often amazed that they can get a custom pin of the highest quality for less than the price of an off-the-shelf pin elsewhere.

For custom prototypes and other small orders (under 100 pieces) we amortize the cost of seven CNC setups over the quantity you order.






SPECIALTY OPTIONS



Recessed button Pin
RECESSED BUTTON PINS
More Info

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.

Adjustable Grip Pin
ADJUSTABLE GRIP PINS
More Info

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.

Double Acting Pin
DOUBLE-ACTING PINS
More Info

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.

Spring Pin
SPRING PULL PINS
More Info

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.

Pin Accessories
QUICK-RELEASE PIN ACCESSORIES
More Info

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.

Custom Ends
CUSTOM END OPTIONS

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!

WHEELCHAIR AXLES

In 1999, Big Sky Precision started making quick-release axles for wheelchairs. Since then we have produced literally hundreds of thousands of these pins that allow for quick removal of wheels for transport, repair or exchange. Our most popular axles have integrated "hubcap" push buttons with custom laser engraving. These hubcaps are available in domed, spherical or flat and can be anodized any color. Shank materials are typically from 17-4 PH stainless. We also manufacture shanks from aluminum (for pediatric wheelchairs), titanium (ultra-light), and Vasco 300 for ultra-strength in rugby competitions and other extreme sports. We produce a ⅝”, bariatric version as well.
