Use these general purpose 18-8 stainless steel screws for a variety of fastening applications. They have good chemical resistance.

Choose these metric screws for fastening most machinery and equipment. They are twice as strong as low-strength steel screws.

More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water.

These alloy steel set screws have a thin edge that digs into hard surfaces for a secure hold. They're available in metric sizes.

About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to class 10.9 nuts.

These nuts have good chemical resistance and may be mildly magnetic. Metric 18-8 stainless steel is also known as A2 stainless steel.

These metric nuts meet JIS (Japanese industrial Standard) B 1181.

These metric nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.

Useful in low-clearance applications, these metric nuts are roughly half the height of standard hex nuts, but aren’t as strong. All are 18-8 stainless steel, which is nearly as strong as steel but won’t rust in outdoor, washdown, and other corrosive environments.

With threads that tighten to the left and made of 316 stainless steel, these nuts won’t loosen from counterclockwise motion in saltwater and corrosive environments. They’re half the height of standard hex nuts, so they fit where there’s low clearance.

Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 2 steel, so they can be used for fastening panels and other light duty fastening applications

Closely spaced metric threads prevent loosening from vibration. These Class 10 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.

Get a grip on metric bolts exposed to vibration, wear, and changes in temperature. These metric locknuts have a nylon insert that holds onto bolts without damaging their threads.

These metric locknuts have good chemical resistance.

With a shorter hex height than standard DIN 985 locknuts, these nylon-insert locknuts meet international ISO 10511 dimensional standards and are easy to install in tight spaces.

These metric locknuts have an irregularly shaped thread at the top of the nut that grips the bolt for a stronger hold than nylon-insert locknuts.

Secure these metric nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance. Often referred to as castle nuts.

Skip the washer—these metric stainless steel nuts have a flange that does the same job, spreading pressure across its surface for a strong hold.

For light duty applications, choose these metric-sized coupling nuts.

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

These metric Grade B7 threaded rods meet the pressure and temperature requirements of ASTM A193 and are often used to secure pressure tanks, valves, and flanges.

About half the strength of medium-strength steel threaded rods, use these metric fine-thread rods for light duty hanging, mounting, and fastening.

These Class 10.9 steel threaded rods are about 25% stronger than medium-strength steel rods.

A distorted thread grips the screw to resist loosening.

Kits include helical inserts, a tap, and an installation tool.

A black-phosphate finish provides mild corrosion resistance.

A black-phosphate finish provides mild corrosion resistance.

Often paired with spring lock washers to strengthen their hold, these retaining nuts—also known as shaft nuts—keep vibration from shifting bearings, bushings, pulleys, and gears on your threaded shaft or spindle.

Also known as nut eyebolts, these are designed for through-hole applications.

Route wire and cable through the smooth eye without snagging.
