Advantages of UNBRAKO® set screws:
- E-Code: Alphanumeric head stamping for traceability
- Rolled thread with narrow tolerances
- Regular inspection for thread faults in manufacture
Hardness class 45H corresponds to a hardness of 450 HV
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.
Tip:
A2/A4 stainless steel set screws are not specially hardened and may be used for tensile loads.
