ISO Nut Standards

This Technical Report gives information concerning the design criteria for nuts specified in ISO 898-2 so that, under static tensile overload, the stripping fracture mode is prevented. The design criteria are also applicable to non-standardized nuts or internally threaded elements with...

SCOPE AND FIELD OF APPLICATION This International Standard specifies clearance hole diameters for general purpose applications. These values result from bearing area calculations in connection with ISO bolt and nut product standards. NOTE - Clearance holes for special applications...

The purpose of this test is to evaluate the axial strength of the nut seat of wheels intended for use on passenger cars, light trucks, and multipurpose vehicles. In addition, a minimum contact area is recommended to ensure enough strength for the rotational force in tightening a nut...

Introduction Note: Nothing in this standard supercedes applicable laws and regulations. Note: In the event of conflict between the English and domestic language, the English language shall take precedence. Purpose. This standard provides acceptance criteria for nuts clinched with or without...

This part of ISO 14960 specifies minimum specifications for clamp-in tubeless tire valves. A clamp-in valve is an assembly of valve stem, valve core, vale cap, rubber grommet or O-ring, hex nut, and ring washer which conforms to ISO 9413.

This European Standard specifies, together with EN 14399- and EN 14399-2, the requirements for assemblies of high-strength structural bolts and nuts of system HRC suitable for preloaded joints, with hexagon head (large widths across flats), cup head or countersunk head, thread sizes M12 to M36 and...

This International Standard specifies the characteristics of prevailing torque hexagon thin nuts (with non-metallic insert) with coarse pitch thread from nominal diameters M3 through M39, with product grade A for nominal diameters M16. NOTE The dimensions of the nuts correspond to those given in...

This CID covers nut butters and nut spreads, packed in commercially acceptable containers, suitable for use by Federal, State, local governments, other interested parties, and as a component of operational rations. Please note: This document does not guarantee purchase of this item by...

This International Standard specifies the geometry of hexagon nuts with nominal thread diameter from 8 mm up to and including 64 mm and the mechanical properties of hexagon regular nuts (style 1) with metric fine pitch thread in product grade A for nominal thread diameters 8 mm ≤ D ≤ 16 mm and in...

This International Standard specifies the characteristics of prevailing torque type hexagon regular nuts (with non-metallic insert) with metric fine pitch thread with nominal thread diameters, D, from 8 mm up to and including 36 mm, in product grade A for sizes D up to and including 16 mm and...

This European Standard specifies, together with EN 14399-1 and EN 14399-2, the requirements for assemblies of high-strength structural bolts and nuts of system HRC suitable for preloaded joints, with hexagon head (large widths across flats), cup head or countersunk head, thread sizes M12 to M36 and...

This standard specifies hexagon nut and washer assemblies for automobiles (herein referred to as nut assemblies). Each nut assembly consists of a washer fitted to a nut by such means as staking the nut collar, to prevent the washer from separating from the...

This specification covers electric nut runner and screwdrivers for tightening nuts, screws and bolts to operate selected, uniform torque (see 6.1).

This standard aims at helping test personnel perform the test in an appropriate method by describing the method of evaluating the presence of fracture in nuts and nut threads when applying the stress to the nut(high strength nut for general automobiles) in the tensile or...
