Also known as try squares, these are square inside and out for checking and marking angles.

Pipe fitting sizes and welding charts are shown on this square in wear-resistant etched markings.

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications.

This material has tighter tolerances than standard 304 stainless steel.

Bend this wire and it will stay put. It’s frequently used as tying wire and locking wire.

This material has tighter tolerances than standard 303 stainless steel.

One side of these sheets has a brushed finish with grain lines running in one direction to mask fingerprints.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications.

This material machines faster with less wear on cutting tools than standard 316 stainless steel. It's also called Prodec and Project 70+.

One of the hardest types of stainless steel after heat treating, 440C offers excellent wear and abrasion resistance. It's often used for bearings, valves, and knife blades.

Precision ground on the top and bottom to a tight tolerance.

One of the most machinable types of stainless steel available, 416 contains sulfur for fast machining without clogging cutting tools. It's used for gears, screws, and shafts.

440A stainless steel resists damage from impact and abrasion. It's often used for cutlery and valve components.

With a higher chromium content than 15-5 PH stainless steel, this high-strength 17-4 PH offers better corrosion resistance. It is also known as 630 stainless steel.

Each piece is precision ground to offer tighter tolerances than standard 17-4 PH stainless steel.

As the most formable of all the PH-grade materials, 17-7 PH stainless steel is widely used in the aerospace industry for intricate parts. When hardened, this material strengthens to make it resist distortion.

The titanium content of 321 stainless steel preserves corrosion resistance around weld points.
