Specification

Notice

Hardness class 45H corresponds to a hardness of 450 HV

The standard tip has an angle of 90°, but very short lengths have an angle of 120°.

ISO 4027 replaces DIN 914 | There is some similarity | Nominal diameters for M1.4, M1.8, M14, M18, M22 are removed | Hardness classes for stainless steels introduced.

Steel set screws are intended for use under compressive stress only (see also DIN EN ISO 898-5). Typical uses include clamping in an adjusting ring or applying pressure to a counterpart. Steel set screws are therefore extremely hard in order to ensure torsional strength in the hexagon socket during tightening/loosening.

Improper application is likely if set screws are welded, tightened and secured with nuts or subjected to bending. Any application of tensile stress is considered improper use and can result in malfunction.

Tip:

A2/A4 stainless steel set screws are not specially hardened and may be used for tensile loads.
