This document specifies the characteristics of parallel grooved pins with pilot point and full-length diamond grooves (with closed-end at the insertion side), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil the main following function: — locking together two or more parts, with the easiest installation (due to the pilot point) and a highest level of pull-out resistance (due to the elastic fit behavior of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts, in steel and stainless steel, with metric fine pitch thread 8 mm to 39 mm, and with product grades A and B.

 

NOTE These nuts are designed with an overall height hmin = mmin (as specified in ISO 898-2 and ISO 8674 for style 2) plus the prevailing torque feature. hmax has been established as a function of hmin, therefore the tolerance (hmax – hmin) does not follow the IT system. mw,min corresponds to the values specified for style 1.

 

If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies the characteristics of prevailing torque hexagon high nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.

 

NOTE These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4033 for style 2) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the nonmetallic insert is identical for regular, high and thin nuts for a given diameter.

 

If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies the characteristics of prevailing torque (all metal) hexagon high nuts with slot(s), in steel and stainless steel, with metric coarse pitch thread M5 to M39, and with product grades A and B.

 

NOTE These nuts are designed with mmin as specified ISO 4032 and with an overall height h greater than in ISO 7042, in order accommodate the prevailing torque feature with slot(s); this height h contributes to the nut resistance due to the number of engaged threads. hmin values have been calculated as a function of hmax together with a ratio hmax/D that progresses regularly with increasing diameter, therefore the tolerance (hmax – hmin) does not follow the IT system.

 

If in certain cases other specifications are requested, property classes and stainless steel grades can be selected from ISO 898-2 or ISO 3506-2.

This document specifies the characteristics of grooved reverse-taper pins with one quarter-length progressive grooves on both sides (close-ends), with rounded or chamfered pin ends, in steel and stainless steel, with nominal diameters 2 mm to 25 mm. These grooved pins are designed to fulfil the main following functions: — relative rotation of the assembled parts, — locking of two (or more) parts, — positioning. The general requirements (including principles for grooved pins and assembly) are specified in ISO 13669.

This document specifies the characteristics of grooved pins with half-length center grooves (with closed ends), in steel and stainless steel, and with a nominal diameter of 1 mm to 25 mm. These grooved pins are designed to fulfill the main following functions: — relative rotation of the assembled parts, and — positioning or guiding, with an easy installation (due to its symmetrical shape) and a high level of pull-out resistance (due to the elastic fit behavior of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

This document specifies the characteristics of grooved pins with one-third-length center grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfill the main following functions: — relative rotation of the assembled parts, and — positioning or guiding, with an easy installation (due to its symmetrical shape) and a medium level of pull-out resistance (due to the elastic fit behavior of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

This document specifies the characteristics of prevailing torque hexagon thin nuts (with non‑metallic insert), in steel and stainless steel, with metric coarse pitch thread M3 to M39, and with product grades A and B.

 

NOTE These nuts are designed with an overall height equal to mmin (as specified in ISO 898-2 and ISO 4035 for style 0) plus the prevailing torque feature. The height of the prevailing torque feature (hmax – mmin) for the nonmetallic insert is identical for regular, high and thin nuts for a given diameter.

 

Nuts with sizes D < M5 and design principles in accordance with style 0 are specified in Annex A.

 

Thin nuts used as jam nuts are to be assembled together with a regular or high nut.

 

WARNING — Thin nuts (style 0) have a reduced loadability compared to regular or high nuts, they are not designed to provide resistance to thread stripping (see ISO 898-2).

 

If in certain cases other specifications are requested, stainless steel grades and property classes can be selected from ISO 3506-2.
