Stainless steel set screws have excellent corrosion resistance in most environments.

The thicker, domed head on these bolts provides greater wear resistance than flat head plow bolts. The underside of the head is angled to sit flush within countersunk holes for use on heavy equipment, such as plows. The square neck keeps these bolts from turning when tightening a nut.

Made from alloy steel, these screws are nearly twice as strong as stainless steel flat head screws.

A nylon patch bonded to the threads of these metric screws adds friction to prevent loosening from vibration. Made of 18-8 stainless steel, they have good chemical resistance and may be mildly magnetic.

Slide the bolt and drop the knob into the notch to secure.

Bolts are spring-loaded to stay latched until you activate the pull.

The mounting screws on these latches are concealed to prevent tampering.

No hands needed—step on the top cap to latch the bolt; retract it by pressing the side release button.
