Sharp internal teeth dig into surfaces to resist large amounts of vibration, while the smooth outside edge provides a finished look. Also known as Sems screws, the washer rotates freely but is permanently attached.

These metric screws have a washer with sharp external teeth that dig into surfaces for maximum holding power and vibration resistance. Also known as Sems screws, the washer rotates freely but is permanently attached.

As you tighten these metric screws, the split lock washer flattens to add tension and prevent loosening from small amounts of vibration. Also known as Sems screws, the washer rotates freely but is permanently attached.

A zinc plating on these metric steel screws provides mild corrosion resistance.

A zinc plating provides mild corrosion resistance.

These metric alloy-steel screws are twice as strong as standard steel Torx flat head screws.

With a reduced head size and an unthreaded shoulder, use these screws as a shaft or dowel pin for small rotating parts in low-clearance applications.

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

A flange provides a bearing surface to hold parts under the head.

Choose these metric bolts for fastening most machinery and equipment. They are twice as strong as low-strength steel bolts. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

Made from Grade 8 steel, these bolts can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Carriage bolts have a smooth, rounded head for a finished look. The square neck keeps these bolts from turning when tightening a nut.

About half the strength of medium-strength bolts, these bolts are for light duty fastening. Carriage bolts have a smooth, rounded head for a finished look. The knurled neck grips the inside of the hole to keep these bolts from turning when tightening a nut.

A Torx drive has more points of contact than a Phillips drive, allowing you to apply extra force with less slippage or damage to the recess.

These steel screws are zinc plated to resist corrosion in wet environments.

Commonly used with door hinge hardware, these screws cut threads in material such as aluminum and brass.

The triangular shank presses tightly as it forms threads, so screws resist loosening in soft metals such as brass, aluminum, and copper.

These screws have a hex head for a secure grip with a wrench.

Cutting their own pilot hole and threads as you fasten them into material, these metric screws have a drilling tip.

Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws.

With a drilling tip, these metric screws cut their own pilot hole and threads as you fasten them into material.

A tamper-resistant Torx driver is required for installation and removal. Also known as pin-in-Torx, these screws allow you to apply extra force with less slippage or damage to the recess.

These steel screws are available with corrosion resistant finishes. A rubber-bonded washer compresses to form a watertight seal. They save you time and effort by drilling their own holes and fastening in a single operation.

Serrations under the head act as a brake to prevent overtightening and damaging threads.
