National foreword

This British Standard has been prepared under the direction of the General Mechanical Engineering Standards Policy Committee and is the English

language version of EN 27435:1992 Slotted set screws with long dog point,

published by the European Committee for Standardization (CEN) It is identical with ISO 7435:1983, published by the International Organization for

Standardization (ISO) EN 27435:1992 was produced as a result of international discussions in which the United Kingdom took an active part

BS 4219-3:1985 which was identical with ISO 7435:1983 is now superseded by this British Standard and has been withdrawn in accordance with the

CEN/CENELEC Internal Regulations

A British Standard does not purport to include all the necessary provisions of a contract Users of British Standards are responsible for their correct application

Compliance with a British Standard does not of itself confer immunity from legal obligations.
