The M3 threaded rod beside the M2.5 and the M4

The M3 is number 3, counting from the smallest, of the 7 DIN 976-1 threaded rods published here, from M2 to M8.

• Rod length (l): 1000 mm on the M3 threaded rod, the same on the M2.5 and the M4.
• Coarse thread pitch (P): 0.5 mm on the M3 threaded rod, against 0.45 mm on the M2.5 and 0.7 mm on the M4.
• Tap drill diameter (tap_drill): 2.5 mm on the M3 threaded rod, against 2.05 mm on the M2.5 and 3.3 mm on the M4.
• Basic minor diameter (d1): 2.458734 mm on the M3 threaded rod, against 2.0128606 mm on the M2.5 and 3.2422276 mm on the M4.
• Chamfered end angle (ch_angle): up to 50° on the M3 threaded rod, the same on the M2.5 and the M4.
• Clearance hole, fine series (dh_fine): 3.2 mm on the M3 threaded rod, against 2.7 mm on the M2.5 and 4.3 mm on the M4.
• Clearance hole, medium series (dh_medium): 3.4 mm on the M3 threaded rod, against 2.9 mm on the M2.5 and 4.5 mm on the M4.
• Clearance hole, coarse series (dh_coarse): 3.6 mm on the M3 threaded rod, against 3.1 mm on the M2.5 and 4.8 mm on the M4.
