Designed for smaller-than-standard through holes, these L-handle latches are often used for securing doors and drawers. They have an attached arm that rotates 90° to hold your enclosure shut. This is why they’re commonly known as quarter-turn latches.

Install these latches on cabinet doors and file drawers with smaller-than-standard through holes. The wing handle makes it harder for clothing and straps to snag on them than cam latches with a T- or L-handle. They have a cam that rotates to lock your enclosure.

Install and remove retention knobs on machine tool holders with steep-taper shanks such as CAT and BT tapers. These sockets are precision machined to fit retention knobs, so you get a solid grip without harming the knob’s surfaces. That’s also why they’re made of hardened steel—they’re durable enough for frequent use yet softer than most knobs to prevent wear on the knob. With no damage to the retention knob, you’ll get a secure connection between the tool holder and your machine’s spindle and drawbar. Use a torque wrench (not included) to tighten the retention knob to your machine’s recommended torque.

They’ll fit most knobs with the listed taper. To ensure compatibility, match your knob’s flat width, head diameter, and flange diameter to the socket dimensions.

Lock tool holders in place on CNC machines with a BT taper spindle. All meet industrial standards for tensile and shear strength. These knobs are also known as pull studs. They have a pilot, which ensures precise alignment between the tool holder and spindle, reducing vibration and runout. To ensure compatibility with your machine, compare the features on these knobs, such as the pilot design, to those on your current knob. If you want to upgrade a standard knob to one with a pilot, confirm that the pilot diameter is small enough to fit in your tool holder without touching the inner walls where the knob seats.

Use a torque wrench with a retention knob socket or a changeable-head torque wrench to tighten them.

Lock tool holders in place on CNC machines with a through-spindle coolant (TSC) system. They fit machines with a BT taper spindle. All meet industrial standards for tensile and shear strength. Also known as pull studs. These knobs have a pilot, which ensures precise alignment between the tool holder and spindle, reducing vibration and runout. To ensure compatibility with your machine, compare the features on these knobs, such as the location of O-ring seals and the pilot design, to those on your current knob. To upgrade a standard knob to one with a pilot, confirm that the pilot diameter is small enough to fit in your tool holder without touching the inner walls where the knob seats.

Lock tool holders in place on CNC machines with CAT taper spindles when milling, drilling, and routing. All meet industrial standards for tensile and shear strength. These knobs are also known as pull studs. To ensure compatibility with your machine, compare the features on these knobs, such as the location of O-ring seals and the pilot design, to those on your current knob. Use a torque wrench with a retention knob socket or a changeable-head torque wrench to tighten them.

Knobs with a pilot ensure precise alignment between the tool holder and spindle, reducing vibration and runout. To upgrade a standard knob to one with a pilot, confirm that the pilot diameter is small enough to fit in your tool holder without touching the inner walls where the knob seats.
