The standard for high-strength fastening.

Choose these metric screws for high-strength fastening. Often used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems, these screws are at least 25% stronger than medium-strength steel screws.

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

Class 8 nuts are comparable in strength to Class 8.8 bolts and are suitable for fastening most machinery and equipment.

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

These metric nuts are about 20% stronger than high strength steel nuts and are often used in heavy machinery.

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.

These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.

Made of 316 stainless steel for excellent corrosion resistance—including in salt water—these nuts tighten to the left and won’t loosen from counterclockwise motion. For use in low-clearance areas, they’re half the height of standard hex nuts.

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

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 metric locknuts have good chemical resistance.

Made from medium-strength steel with a nylon insert, these Class 8 metric locknuts are strong enough to use on most machinery and equipment that’s prone to vibration and temperature changes.

A nylon insert keeps metric bolt threads from coming loose due to vibration, wear, and temperature swings. About 25% stronger than medium-strength steel locknuts, these nuts are made of high-strength, Class 10 steel.

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.

Strong enough for use with most machinery and equipment, these Class 8 metric locknuts have an irregularly shaped thread in the middle of the nut that grips bolts tighter than nylon-insert locknuts.

Choose these locknuts to fasten standard metric threads. They’re Class 8 steel, so they can be used in most fastening applications.

These metric coupling nuts have good chemical resistance.

Made from 18-8 stainless steel, these metric nuts have good chemical resistance and may be mildly magnetic.

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.

Inserts come with a through-hole tap and installation tool.

Made of 18-8 stainless steel, these inserts have good corrosion resistance.

These inserts come with an installation tool. Drive the keys into the surrounding material for a more secure hold than thread-locking inserts.

With a nylon insert that grips your threaded shaft or spindle without damaging the threads, these locknuts—sometimes called shaft nuts—keep bearings, bushings, gears, and pulleys in place.

Used in pairs or with another bearing retaining nut, these jam nuts—often called shaft nuts—hold bearings, bushings, pulleys, and gears in place on your threaded shaft or spindle.

Also known as machinery eyebolts.

Unlike conventional eyebolts, you can rotate the eye 360° to match the angle of your load.
