Then bằng kiểu cao làm bằng thép then bề mặt sáng truyền mô-men xoắn qua các mặt bên song song. DIN 6885-1:2021-11 quy định mười bốn dạng. Hai đầu then đều tròn (A, AS, C, E, EoS), đều vuông (B, BS, D, F, FoS, G, H, J) hoặc một đầu tròn và một đầu vuông (AB). C, D và G có một lỗ cố định có bậc trụ, E, F, H, EoS và FoS có hai lỗ. AS và BS, cùng E và F từ tiết diện 12 × 8, có lỗ ren tháo. G, H và J có phần vát thoát 15° ở một đầu; J còn có lỗ chốt đàn hồi. Ký hiệu nêu dạng, chiều rộng, chiều cao và chiều dài.
