STAINLESS STEEL HALF LENGTH REVERSE TAPER GROOVED PINS DIN 1474

Half Length Reverse Taper Grooved Pins DIN 1474 — Half Length Reverse Taper Grooved Pins to DIN 1474 are grooved over half their length in the same way as DIN 1472, but with the taper and grooved section positioned at the opposite end relative to the plain shank — effectively a mirror image of that pin. The practical reason to specify DIN 1474 rather than DIN 1472 is assembly geometry: some joints need the gripping, grooved section to sit at the far end of the pin from where it's driven in, rather than at the leading, piloted end, and DIN 1474 is made for exactly that orientation. Functionally it behaves the same way as any half-length grooved pin — firm retention concentrated in one component, with the plain half sitting in, or passing through, a second part without gripping it — so it suits the same kind of assemblies as DIN 1472: brackets, levers, or fittings where only one side of the joint should be locked to the pin while the other allows slight movement or simple pass-through. As with other grooved pins, no reamed hole is required; a standard drilled hole in the grooved section is sufficient, since the ridges themselves generate the interference fit rather than depending on hole tolerance. Deciding between DIN 1474 and DIN 1472 comes down entirely to which end of the assembly needs the self-locking grip once installed — this is a drawing and assembly-sequence decision rather than a performance difference between the two, since the pins are otherwise equivalent in grip mechanism and load capacity for a given diameter. Grade selection is the same as elsewhere in the range: A2 stainless for typical indoor mechanical assembly, A4 where outdoor, washdown, marine, or de-icing salt exposure would otherwise degrade the grooved section's grip over time through pitting. Diameter and length should be selected so the grooved half fully engages the gripping component and the plain half suits the fit needed in the second.

FAQs
How does DIN 1474 differ from DIN 1472?
Both are half-length grooved pins; the position of the grooved, gripping section relative to the plain shank is reversed between the two, so the choice depends on which end of the joint needs the grip.

Are DIN 1474 pins interchangeable with DIN 1472 if the orientation doesn't matter?
Only if the assembly is symmetrical enough that grip position genuinely doesn't matter — in most cases the two are specified deliberately for a particular assembly direction, so they shouldn't be treated as freely interchangeable without checking the drawing.

What load direction is this pin best suited to?
Like other half-length grooved pins, it's intended primarily for locating and light shear loads rather than significant axial pull-out resistance from the plain end — where strong retention is needed along the whole length, a full-length grooved pin such as DIN 1471 or DIN 1473 is the better choice.
