This document specifies the boundary dimensions and tolerances for Types A to D of roller blocks.

Roller blocks Types E and F are given in an informative Annex. They require fixing parts and are not yet produced on a broad manufacturer base.

The internal design of roller blocks is at the discretion of the manufacturer.

This document specifies the characteristics of hexalobular socket set screws with threads from M3 up to and including M30 and of product grade A.

ISO 4028:2003 specifies the characteristics of hexagon socket set screws with dog point and threads from M1,6 up to and including M24 and of product grade A.

This document specifies the characteristics of grooved pins with half-length centre oval grooves (with closed ends), in steel and stainless steel, and with nominal diameter 1 mm to 25 mm. These grooved pins are designed to fulfil 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 behaviour of the pin). The general requirements (including functional principles for grooved pins and assembly) are specified in ISO 13669.

ISO 4026:2003 specifies the characteristics of hexagon socket set screws with flat point and threads from M1,6 up to and including M24 and of product grade A.

ISO 4029:2003 specifies the characteristics of hexagon socket set screws with cup point and threads from M1,6 up to and including M24 and of product grade A.
