T-head bolts with double nib

Hammerschrauben mit Nase

Supersedes January 1971 edition.

In keeping with current practice in standards published by the International Organization for Standardization (ISO), a comma has been used throughout as the decimal marker.

Dimensions in mm

1 Scope and field of application

This standard specifies M 8 to M 80 X 6 T-head bolts with double nib. They are designed for use in attaching components to foundations or similar structures by means of T-slots, such as are specified in DIN 649, where T-head bolts with square neck are considered adequate detachable fasteners.

2 Dimensions

DIN 78 – K or DIN 78 – L thread end, at the manufacturer's discretion.

u (incomplete thread); 2 P maximum.

Lengths above 400 mm shall be graded in 20 mm steps. Bracketed sizes should be avoided if possible. T-head bolts with double nib are normally manufactured in sizes for which shank lengths have been specified.

_g max. = l (nominal lengths) − b (auxiliary size) shall apply for screws with lengths below the stepped line;

_s min. = _g max. − 5 P.

1) P = pitch of thread (coarse pitch thread).

2) For l up to and including 120 mm.

3) For l above 120 up to and including 200 mm.

4) For l exceeding 200 mm.

5) e min. = n min. × 1,41 − 0,82 × r₂ max.

6) r₂ max. = 0,15 d.
