T-head bolts with square neck

Hammerschrauben mit Vierkant

Supersedes January 1987 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 6 to M 48 T-head bolts with square neck. 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

Type A, with thread end

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

u (incomplete thread); 2P maximum.

Type B, with shank fully threaded

Lengths above 200 mm shall be graded in 20 mm steps. For these sizes, b is to be calculated from: b = 2d + 25 mm.

Bracketed sizes should be avoided if possible.

The range of commercial sizes has been indicated by continuous stepped lines. The space between the dashed and the upper continuous stepped line applies only to type B bolts, for which l_s and l_g values have been specified in the upper half of the table.

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

5) r₂ max. = 0,15 d.

6) l_s min. = l_g max. − 5 P.

7) l_g max. = l (nominal size) − b.
