T-head bolts

Hammerschrauben

Supersedes December 1970 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 100 X 6 T-head bolts. 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 are considered adequate detachable fasteners.

2 Dimensions

With normal shank (commercial for sizes up to and including M 36)

(bolt sizes up to and including M 100 X 6 also permissible, at the manufacturer's discretion)

1:20

u (incomplete thread); 2P maximum.

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

With reduced shank (commercial from size M 42)

For 1), see clause 4.

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

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

l_s min. = l_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.

4 Designation

Designation of an M 20 T-head bolt, of nominal length l = 120 mm:

T-head bolt DIN 261 — M 20 × 120

Normally, the internal thread diameter, d_b, is to be specified for T-head bolts exceeding a mass of 10 kg and shall be particularly agreed upon when ordering. The designation shall then read, e.g.:

T-head bolt DIN 261 — M 72 × 6 × 400 × M 16
