Use these steel set screws for light duty holding.

More corrosion resistant than 18-8 stainless steel set screws, these have excellent resistance to chemicals and salt water.

These metric screws have a square head, so you can turn them by hand or use a wrench for more torque. Also known as half dog-point set screws, they have a protruding tip that locks within a mating hole or slot to keep parts aligned.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Large flat sides make these screws easy to grip with a wrench and keep them from rotating in square holes.

Attach to Starrett High-Accuracy Combination Square Blades with the included lockbolts.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

Use these fittings for low-pressure applications in noncorrosive environments.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

Extreme pressures are no problem for these heavy-duty brass fittings.

The male threads on these fittings have a sealant applied for extra leak protection.

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

Designed for medium-pressure applications, these fittings have better strength than our low-pressure aluminum pipe fittings.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Extreme temperatures are no problem for these fittings—they’re made of PTFE, so they can withstand a wider temperature range than any of our other plastic pipe fittings for chemicals. They are commonly used in high-purity chemical flow processes, such as semiconductor and clean room applications.

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.

More durable than plastic plugs, these provide the most protection from abrasion and impact. Use them to eliminate sharp edges and create a finished look on metal fence and machine-guard posts. Drive them in place with a hammer for a secure fit.

Flexible ridges or straps hold these plugs in place.

Protect internally threaded NPT connections from contaminants during fabrication and storage.

Flexible ridges securely hold these plugs in place and allow them to fit a range of hole sizes.

Shield USB connectors from damage, contaminants, and moisture when they are not being used.

Slide these flexible vinyl caps onto rectangular objects and they conform for a snug fit.

Made of rigid plastic, these caps are more wear resistant than vinyl caps but not as flexible.
