These metric thumb screws have a knurled head for a slip-resistant controlled adjustment.

Arms provide a flat surface to push your fingers against.

These metric thumb screws have a large head that allows you to grip them with your entire hand for greater torque while tightening than standard knurled plastic-head thumb screws.

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

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

Wings provide more leverage than spade-head thumb screws for greater torque while tightening. A zinc plating provides corrosion resistance in wet environments.

These metric thumb screws have arms that provide a flat surface to push your fingers against.

These metric thumb screws are made of chemical-resistant 18-8 stainless steel. Also known as dog- and pilot-point thumb screws, insert the point into a drilled hole or slot to hold items in place.

For maximum contact with angled and uneven surfaces, the tip swivels in all directions. The tip is narrow so it will fit through threaded holes.

A wide tip provides more gripping power than standard swivel-tip thumb screws. To use, remove the tip, thread the screw through the hole, and attach the tip on the other side.

These steel thumb screws have a black-oxide finish to resist corrosion in dry environments.

Snap these screws into panels up to 0.125" thick—no tools are required for installation.

Install in soft material such as aluminum and low-carbon steel at least 0.036" thick with an arbor press or similar pressure tool.

These wing-head screws have a clip-on nut that allows you to mount them near the edge of a thin panel. Use them to lock and release access panels, doors, and covers with a quarter-turn.

Press these wing head nuts into a closed-end hole or thick panel in applications where the back of the panel is inaccessible. A quarter-turn locks and releases access panels, doors, and covers.
