Coupling nuts, also known as extension nuts, are threaded fasteners used for joining two male threaded rods. The exterior of this fastener is typically a hex so a wrench can hold it easily. We offer a variety of stainless steel coupling nuts in a range of sizes.Rod Coupling Nuts are used to join two externally threaded objects, usually threaded rod, together. Reducing Coupling Nuts are available to couple two or more studs of different diameters together.

Commonly found in farm, road construction, and other heavy equipment, plow bolts are heavy duty fasteners with non-protruding heads. A square neck prevents turning of the bolt.For heavy machinery, we offer two types of plow bolts: those with flat heads and those with domed heads. Both types have a countersunk head and square neck to prevent turning when the nut is tightened or removed. Primarily used in gang plows, road graders, snowplows, and similar heavy equipment, these bolts are durable and reliable.

Socket head cap screws, also known as Allen head screws, are exclusive high-strength tension fasteners that are specifically designed for clamping assemblies. Socket screws are primarily used in tool and die fixture applications; however, due to their unique head design, ultra-durable and reliable socket Allen bolts can be used for a wide range of applicationsSocket cap screws are commonly used in machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets

Nylon Insert Lock nuts have a nylon ring that when tightened on a bolt, resists loosening under all types of vibrations and torque. JM Hardware nylon insert locknuts are available in a variety of sizes and materials including low and medium carbon, heat treatable steel grades, including non-ferrous materials.If you are looking for a threaded fastener that will resist loosening, then nylon insert locknuts are the best solution for your project. Used for industrial purposes or in the Aerospace industry, this fastener is reliable and durable.

Slotted nuts, also known as castellated nuts, have grooved heads that align with holes in the mated bolt to accept the insertion of a cotter pin, locking the nut in place. They are commonly used to ensure that shaft components in certain automotive assemblies do not separate or to maintain machine settings in manufacturing environments.Slotted Hex Nuts have opposed slots cut into the top of the hex nut through the center of flats. Slots are cut into the non-bearing surface of the nut. Used for general purpose fastening and locking, slotted hex nuts can be used with cotter pins or safety wire through the slots and through the hole drilled shank of the fastener.

Clevis PinComprising one of three parts in a clevis fastener system, clevis pins absorb lateral stress and rotate to allow freedom of movement for supported objects. Clevis pins are found in land, sea, and air vehicles, agricultural machinery, and construction applications.Lynch PinLynch pins are often used to keep a wheel in place on its axis. These pins may be found in agricultural settings, and like hitch pins, are used to secure vehicle trailers.Hairpin Cotter PinHairpin Cotter Pins, often referred to as hitch pin clips, R-clips, or R-keys, secure the ends of hitch pins by being inserted into a hole at the end of the hitch pin to eliminate the chance of the pin falling out. These are most often found securing pins in wheels, axles, rotary machines and trailer hitches.Cotter PinCotter pins, also called split pins, are equipped with two tines that bend during application. These metal fasteners lock in place during installation when the two ends of the cotter pin are bent apart, an...

T Bolt are resistant to corrosion, aesthetics, rust and other high-quality characteristics. They have high strength and good impact resistance. Their mechanical properties are far superior to ordinary bolts. The performance is continuously improved and the application fields are becoming wider and wider. T-type screw, also known as T-head bolt, European standard is called hammer type bolt, the material is stainless steel and carbon steel, carbon steel T-type screw surface can be galvanized or nickel plated and plated up to Crowe, carbon steel T-head bolt The material is 1045 medium carbon steel, which is produced by red satin process. After heat treatment, the grade is 8.8. Generally, it is a mold platen bolt. The T-screw can be directly placed in the groove. It can be automatically positioned and locked during the installation process. T-bolt Generally used with flange nuts, it is the standard connecting fastener when installing the corner piece. T-bolt is selected according to the...
