Save time and effort with screws that drill and fasten in one step. The hex head gives you a firm, high-torque grip with a nutdriver or socket. Screws have a flange under the head that spreads the load to prevent crushing thin metal.

Length is measured from under the flange. Head height includes the flange.

Often used on posts and beams, the coarse threads on these screws dig in for a firm hold. The hex head's six contact points keep sockets in place to avoid slipping and stripping the drive. To tighten, use a wrench or six-point hex socket. Also known as lag bolts.

Drill a pilot hole slightly smaller than the screw to prevent splitting. Length is measured from under the head.

Prevent cracking and splitting brittle materials such as phenolic and glass-filled plastic. These screws have alternating high and low threads that minimize stress on your workpiece. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.

Length is measured from under the head.

With no point at the tip, these screws reduce the chance of damaging sheet metal. Install them in a drilled hole and the fine threads form a vibration-resistant hold. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.

Length is measured from under the head.

Attach tarps and fabric to metal surfaces. These screws have an attached, free-spinning washer that stays put as you tighten to prevent bunching the material. They save time by drilling and fastening in one step.

Length is measured from the edge of the head.

Align, position, and lock moving parts for most machining and assembly tasks. These spring plungers have a spring-loaded ball that compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place. Unlike long-nose spring plungers, the ball rolls easily in and out of position, so they're a great fit for applications that require consistent, smooth movement, such as positioning parts in an assembly line and aligning fixtures and jigs when cutting or drilling.

Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.

Thread these screws into molded or cast holes in plastic without installing inserts. They won’t crack or distort material when fastening enclosures, panels, and other plastic components. The Phillips drive handles enough torque to keep drivers from slipping and the rounded head creates a finished look.

Length is measured from under the head.

When you can't tap threads in your mounting surface, push these spring plungers into unthreaded holes. They work well in wood, plastic, and other soft materials that might crack if you try to cut threads. The spring-loaded ball compresses when a part presses against it, and then pops out into a notch or groove to hold the part in place.

For a snug fit, use an arbor press to install these spring plungers in a slightly smaller hole than the body diameter.
