The standard for high-strength fastening.
Made from Grade 8 steel, these screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws.
Twice as strong as low-strength steel screws, these screws are suitable for fastening most machinery and equipment.
These nuts are suitable for fastening most machinery and equipment.
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion.
About half the strength of medium-strength steel nuts, these nuts are for light duty fastening applications.
These nuts are about 25% stronger than medium-strength steel nuts.
Tighten these nuts by turning them to the left; once fastened, they resist loosening from counterclockwise motion.
These nuts have good chemical resistance and may be mildly magnetic.
These nuts have excellent chemical resistance and can be used in saltwater 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.
Made from Grade 5 steel, these inch-sized nuts are suitable for most fastening applications.
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. They’re Grade 5 steel, so you can used these inch-sized nuts for most fastening applications.
These nuts should be used for light duty fastening applications, such as securing access panels.
These nuts tighten when turned to the left; once fastened, they resist loosening from counterclockwise motion. Made of Grade 2 steel, these nuts can be used for fastening panels and other light duty fastening applications.
These nuts are about 25% stronger than medium-strength steel thin hex nuts. Available in inch thread sizes.
These nuts are corrosion resistant in wet environments, electrically conductive, and nonmagnetic.
Because they’re about 10% wider and taller than standard hex nuts, these heavy hex nuts distribute the load over a large area. Grade 2H nuts are comparable in strength to Grade 9 bolts.
Taller than standard hex nuts, these nuts provide a larger gripping area for installation with a wrench.
Includes inch thread sizes. These Grade 8 steel locknuts are 25% stronger than our medium-strength steel nylon-insert locknuts.
These locknuts are about half the height of standard nylon-insert locknuts. Use them in light duty low clearance applications or jam one against a hex nut to hold it in place.
These Grade 8 locknuts are about 25% stronger than medium-strength steel thin locknuts.
Grade 5 locknuts are suitable for fastening most machinery and equipment when used in conjunction with a standard hex nut.
These locknuts have good chemical resistance and may be mildly magnetic.
Comparable in strength to Grade 8 bolts, these locknuts are about three times stronger than the same locknut made with low-strength steel.
Comparable in strength to Grade 8 bolts, these locknuts are about 25% stronger than medium-strength steel locknuts.
Known for their strength, these steel locknuts are cadmium plated to resist corrosion in wet environments.
Also known as castle nuts, secure these nuts by inserting a cotter pin or safety wire through the slots and a drilled hole in your bolt for mild loosening resistance.
About half the strength of medium-strength steel locknuts, these are for light duty fastening applications, such as securing access panels.
When installed, the steel insert grips the threads and lifts away from the nut body, isolating the insert from the nut's load to resist spinoff caused by vibration.
About two-thirds the height of standard steel-insert locknuts, use these locknuts in low-clearance applications or jam one against a hex nut to hold it in place.
About half the strength of medium-strength steel coupling nuts, these nuts are for light duty fastening applications.
Made from Grade 8 steel, these nuts are about 25% stronger than medium-strength steel coupling nuts. Furnished in inch thread sizes.
These cap nuts have excellent resistance to chemicals and salt water.
About half the strength of medium-strength steel cap nuts, use them in light duty fastening applications, such as securing access panels.
About half the strength of medium-strength steel coupling nuts, these metric nuts are for light duty fastening applications.
Use these tube-end weld nuts with left-hand threaded fasteners.
Grade B7, these threaded rods have a tensile strength about one and a half times stronger than low-strength steel rods. They 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 for light duty hanging, mounting, and fastening.
Comparable to Grade 8 steel, these threaded rods have a tensile strength of 150,000 psi, making them about 25% stronger than medium-strength steel rods.
Inserts come with a through-hole tap and installation tool.
A black-phosphate finish provides mild 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.
Also known as CGA nuts, these are designed for low-pressure welding applications downstream of your pressure regulator. Attach them to barbed hose fittings for compressed gas to make a threaded connection to torches or pressure regulators.
Also known as machinery eyebolts.
Combine with mounting blocks to mount and secure threaded-body shock absorbers.
