Introduction
This standard conforms in substance to International Standard ISO 299:1987.
farewell letterIn conjunction with DIN 6379 studs, nuts for T-slots form clamping elements similar in function to the T-head bolts specified in DIN 787.
DIN 267-4 (withdrawn), upon which the April 1991 edition of this standard was bad, was superded by DIN EN 20898-2. However, neither the property class specified in the latter standard nor the hardness class specified in DIN 267-24 apply becau the T-nuts specified here are not compatible with conven-tional nuts. Instead, T-nuts as specified in this standard shall be subjected to tensile testing using the proof loads specified in table 1 (cf. figure 2).
To utilize the bearing capacity of T-nuts, full-length engagement of the stud is esntial. It should be noted that, when determining the bearing capacity of the asmbly, allowance must be made for the reduced wall thickness of the shank.
