Description Six-sided internally threaded fasteners whose thickness is .875 D where D is the nominal nut size and 1.5D is their width across the flats,made from austenitic alloys as described below.


Designed for use with stainless steel bolts and screws with a specified minimum tensile strength equal to or less than the specified proofstress of the mating nut. Both types of stainless are corrosion resistant with 316 stainless having greater such resistance as well as

superior strength at raised temperatures.

Material18-8: Nuts shall be made from one of the following austenitic alloys: 303, 303Se, 304, XM7, all of which are characterized as having a

chromium content of 18% and nickel content of 8-10%.316: Nuts shall be made from 316 stainless steel, an austenitic alloy which differs from 18-8 by its molybdenum content (2-3%) and a

higher nickel content (10-14%).

HeatTreatment

The austenitic alloys develop their strength through work hardening during the fastener manufacturing process, as seen from the hardnessproperties below. The only heat treatment normally available on austenitic stainless alloys is annealing, which is done at approximately

19000F to a dead soft condition and is not normally thermally reversible.

DescriptionA six-sided internally threaded fastener which is both thicker and wider across the flats than a same-sized finished hex nut, made of 18-8 stainless steel. Nuts in sizes 7/16 & smaller shall be double chamfered. Larger sizes are either double chamfered or chamfered on

top with a washer faced bearing surface.


This is the strongest of all 18-8 stainless hex nuts because of its greater length of thread engagement and greater resistance to dilation(widening or stretching).

Material Nuts shall be made from one of the following austenitic stainless alloys: 303, 303Se, 304, XM7, all of which are characterized as havinga chromium content of 18% and a nickel content of 8%.

DescriptionGrade-C Automation Lock Nut: An all-metal, one-piece hex nut which derives its prevailing torque characteristics from controlled

distortion of its top threads from their normal helical form to a more elliptical shape.Grade-GT Flange Style Automation Lock Nut: Similar to Grade-C but with a flange on the bottom side of the nut.


Grade-C: These nuts are reusable and can withstand temperatures of up to 4500F. Can withstand severe vibration and shock loads.Frequently used in farm machinery, plus the automotive and related metalworking industries.

Grade-GT: Has a lower, more uniform bearing stress to clamp force ratio. This style reduces inventory (by eliminating a washer) and in-place cost. It is designed to be used specifically but not exclusively with grade-8 frame bolts.

Material C1022 - 1045 steel.

Heat Treatment Nuts are heat treated to the austenitizing temperature of the material of which the nut is made, quenched in a proper medium to obtain apredominately martensitic microstructure, and tempered to the specified hardness.

This is the least expensive prevailing torque type of nut, designed for use with machine screws and low-carbon bolts. It allows forautomatic assembly because the top and bottom of the nut are identical. It creates a locking action even without being fully threaded

onto its mating screw.

Material Nuts shall be made from a low-carbon steel which conforms to the following chemical composition requirements--Carbon: 0.47%max.; Phosphorus: 0.12% max.; Sulfur: 0.23% max..

Hardness Rockwell C28 maximum

®Esna is a registered trademark of the MacLean-Fogg Company. Kanebridge’s stop nuts are not manufactured by or connected with the producers of Esna® nuts.

DescriptionHeat treated hex nut with a nylon-filled collar at its back end. The nut shall be grade-marked in one of two ways: (1) with double

notched corners or (2) with six symmetrically spaced identical symbols on the chamfered surface on top of the nut. When the cap-screw or bolt reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the cap-screw or bolt when it

is subjected to vibration. The nylon insert comes in various colors.


Designed to be used in structural applications with Grade-8 cap-screws or bolts which have a minimum tensile strength of 150,000 psi.or greater. Some such applications include engines, turbines, hydraulic cylinders, railroads and aerospace. Nylon insert nuts are not

designed to be used at temperatures over 250 0 F.

Material Heat treated AISI C1137 or equivalent steel.

Heat Treatment Nuts are heated to the austenitizing temperature of the steel, quenched and tempered to achieve the hardness specifications listed inthis table.

Hardness Rockwell C 26 - 34


Plating Grade-8 nylon insert stop nuts are usually supplied zinc yellow-plated. See Appendix-A for more information.

DescriptionAn all-metal, one-piece, hex-shaped lock nut with a round collar at its back end. The collar is segmented with opposed slots cut into it

above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands which creates the prevailingtorque locking action. The light hex variety has a lesser across the flats dimension resulting in a lighter-weight part with the same

strength as a heavy hex variety.


The full height light hex lock nut has the same locking capability as the heavy hex FlexLoc® nut, but with greater wrench clearance.FlexLoc nuts maintain their locking strength through 15 removals and re-applications, and at temperatures up to 550°F (450°F if zinc

or cadmium plated). They have superior resistance to vibration compared to all other lock nut varieties and do not gall threads.

Material Carbon steel.

Tensile Strength Minimum tensile strength requirements for carbon steel FlexLoc nuts are listed in above table.

Plating Unless specified as plain steel, FlexLoc nuts are used with a zinc, zinc yellow or cadmium finish.

above each corner of the nut. When the screw or bolt reaches the collar, the slotted portion expands which creates the prevailingtorque locking action. The light hex, thin height variety is approximately 30% shorter than the full height nut.


The thin height light hex FlexLoc® nut is used when an insufficient number of projecting threads are present to use a full height nut,or when a lighter-weight nut is required. FlexLoc nuts maintain their locking strength through 15 removals and re-applications, and attemperatures up to 550°F (450°F if zinc or cadmium plated). They have superior resistance to vibration compared to all other lock

nut varieties and do not gall threads.

Wing Nuts Washer BaseZinc Alloy

Description A zinc alloy nut featuring a wide-diameter, integral washer base with a recessed wing design.


Suitable for most wing nut applications, specifically in those where a separate flat washer would be used. Integral washer designeliminates need for other washers and speeds assembly time. Used with adjustment slots, oversized or offset holes, and soft surfaces

such as wood or plastic. Popular in displays, furniture and storm windows.

Material

Nuts are made from the zinc die cast alloy Zamak #3 which conforms to the following chemical composition requirements--Aluminum: 3.5-4.3%; Magnesium: 0.02-0.05%; Copper: 0.25%* max.; Iron: 0.10% max.; Lead: 0.005% max.; Cadmium: 0.004% max.;

Tin: 0.003% max.; Zinc: balance (*Note: Most commercial applications will accept copper content within the range of 0.25-0.75% withoutrejecting the product).
