Castle Nuts
Castle nuts are a tall lock nut. This nut has slits allowing for insertion of a cotter pin or wire in both the nut and a hole in its bolt, this would prevent the nut from coming loose. Slots are cut into a cylindrical form equal to the slot depth, but smaller than the hex diameter.
|
|
|
|
|
Center Lock Nuts
Another type of locking hex nut that is dimpled on two sides of the hex that is designed to mesh thread against thread to resist reversing.
|
|
|
|
|
Coupling Nuts
Hex coupling nuts are used to connect two pieces of threaded material. Hex couplers are right hand threaded.
|
|
|
|
|
Flange Lock Nut
Flange Nuts have ratchet teeth on underside to help with tightening and resist loosening. Flange base can span oversized clearance holes.
|
|
|
|
|
Flange Nut Stainless
Flange Nuts have ratchet teeth on underside to help with tightening and resist loosening. Flange base can span oversized clearance holes. Stainless steel is used where corrosion resistance is needed.
|
|
|
|
|
Flange Whiz Nuts
One piece all metal nut and washer, with self locking nut. Simply spins on to mating thread and locks when seated to material. Available in metric and standard threads.
|
|
|
|
|
Galvanized
Galvanized nuts have the added corrosion protection with the thicker coat of the zinc process, usually from 1 mil to 4 mil thick.
|
|
|
|
|
Grade 2
A low carbon hex nut used in general assembly where strength in the steel is not critical.
|
|
|
|
|
Grade 5
A medium carbon steel nut used for assembly and production where tensile strength and temperature is not an issue.
|
|
|
|
|
Grade 8
High strength nuts, designed to prevent pulling in the threaded material with higher tensile strength, usually plated in a zinc yellow dichromate.
|
|
|
|
|
Heavy
A structural hex nut used where material specifications are applied to critical applications, such as high pressure and higher temperature applications.
|
|
|
|
|
Heavy Brass
A brass heavy hex nut, does not lend to higher tensile strength, but does offer a wider face surface for bearing.
|
|
|
|
|
Heavy Stainless
A structural hex nut used where material specifications are applied to critical applications, such as high pressure and higher temperature applications, stainless grade is an ASTM A194 B8 spec.
|

|
|
Hex Jam Nuts
Hex jam nuts are thinner than a standard hex nut, but have the same dimension across the flat surfaces and corners. Hex jam nuts have two common applications: They can be run tight against regular nuts to lock them in place, or are used for leveling purpose.
|
|
|
|
|
High Nuts
High Nuts, or Tall Nuts are taller than standard nuts. Their extra height allows for more threads inside the nut, which will provide added strength.
|
|
|
|
|
Jam Lock Nuts
A thin pattern lock nut used for fastening to a bolt when joining materials together. The threads are slightly tappered at the end causing the bolt and nut to mesh together. Preventing the nut from loosening.
|
|
|
|
|
K-Lock
K Locknut is a nut with an external starwasher pre-attched to the one side of the bearing surface used for gripping the surface when tightened.
|
|
|
|
|
K-Lock Stainless
K Locknut is a nut with an external starwasher pre-attched to the one side of the bearing surface used for gripping the surface when tightened. Stainless adds to the corrossion resistance.
|
|
|
|
|
Left Hand
Left hand or reverse thread fasteners are designed to stay tightened in a clockwise rotation of the thread.
|
|
|
|
|
Lock Nuts
Lock nuts are used for fastening to a bolt when joining materials together. The bolt threads into the nut with some type of locking located at the top, side, or dimpled into the thread of the nut, preventing the nut from loosening in a variety of applications.
|
|
|
|
|
Metric
Zinc plated and plain, Class 8(Lo Carbon), Class 10(Thru Hard), Locking, Coarse, and various fine threads.
|
|
|
|
|
Nylon
Nylon 6/6 Hex Nuts are non-corrosive and will are designed absorb minor vibrations, are
non-conductive.
|
|
|
|
|
Propell Nut
Propell nuts are generally used in lumber applications. Propell nuts excel in applications where there is a danger of splitting, either due to material hardness or material thickness. They are also good for end-grain applications, such as leveler feet.
|
|
|
|
|
Silicone Bronze
Silicon bronze is an alloy made of 95-98% copper plus trace amounts of silicon for strength. It is a low to moderate conductor of electricity, although better than stainless.
|
|
|
|
|
Slotted Hex Nut
The hex slotted nut features slots for the insertion of a small pin, for locking purposes. It is as thick as the standard hex nut.
|
|
|
|
|
Square Nuts
Square nuts are typically used in conjunction with square bolts or are commonly used with pole line hardware. Square nuts are also available in stainless steel.
|
|
|
|
|
Stainless 18.8
Commercial grade 18-8(304) stainless used for corrossion resistance.
|
|
|
|
|
Stainless 316
316 Grade stainless is a higher corrossion resistant material to chloride and sulfides with a lower carbon content and higher molybdenum.
|
|
|
|
|
Tee Nut
Designed to be recessed into wood. Tee Nuts have teeth that secure and lock them into wood.
|
|
|
|
|
Wing Nuts
Wing nuts are generally used in marine oriented applications, such as on boats or other sea going vessels. The need for wing nuts has evolved from the need for the speed and convenience tightening and loosening a wing nut by hand. Wing nuts are also used in a variety of other applications in addition to marine.
