Positive Locking VS Detent

Positive Locking vs. Detent, What’s the Big Difference?

Positive locking pins are push-button devices that incorporate a solid stainless-steel spindle with a necked-down waist area. In its at-rest position, the major diameter of the spindle secures the balls in their extended position. When the push-button is activated, the spindle's waist area moves under the balls, allowing them to retract inside of the shank. This causes the pins to be very strong in tension. For example, a 1/2" 17-4, 2-ball pin is rated at 1,160 pounds of pull-out strength!

Detent pins incorporate a very different mechanism. A cross-hole is drilled part way through the pin and then a spring and ball are pressed down in. The hole is swaged (Machined Ball Retention not possible) and the resulting pin can now be moved simply by pulling on it; often just a few pounds of force will pull the pin free. The advantage of detent pins is their low cost for non-critical applications. If safety is a concern, you’d best stick with positive locking.


MACHINED HANDLES

Machined Handles

Why Machined Handles? Four Big Reasons:

1. STRENGTH: Cast handles are brittle. Whether in aluminum or stainless, handles are always stronger when machined from billet.

2. APPEARANCE: One look shows the obvious quality of Big Sky Precision’s machined handles over a cast one.

3. DESIGN FLEXIBILITY: Since there are no mold costs, we can make a custom handle for you - often at the same price as inferior cast handles.

4. CORROSION RESISTANCE: Porous cast handles are susceptible to corrosion & cracking, especially in marine environments., We typically machine handles from 6061 aluminum and 303 stainless.
