STAINLESS STEEL FULL LENGTH PARALLEL GROOVED PIN DIN 1473

Full Length Parallel Grooved Pin DIN 1473 — Full Length Parallel Grooved Pins to DIN 1473 are grooved along their entire length like DIN 1471, but with a parallel, constant-depth groove profile instead of a tapering one, so the interference fit — and the resulting grip — stays more consistent along the whole length of engagement rather than concentrating more toward one end. That even distribution of grip is the main reason to choose this over the tapered full-length version: applications where the retaining force needs to be uniform along the pin's full depth benefit from the more predictable, constant resistance a parallel groove provides. As with any grooved pin, DIN 1473 is designed for a standard drilled hole rather than a reamed one — the grooves generate their own grip through controlled interference, so no dowel-pin-level hole tolerance is needed, which keeps hole preparation simple and low-cost. With chamfers typically formed at both ends, insertion direction is often less critical than with a tapered variant, though this is worth confirming against the specific size before assuming a pin can be driven in from either end without issue. Choosing this over DIN 1471 mainly comes down to whether a uniform grip profile matters more than the taper's characteristic higher engagement force toward full depth — for most general locating and light shear applications either will perform adequately, and the choice is often one of specification preference or drawing convention rather than a hard technical requirement. Grade follows the usual logic for this pin family: A2 stainless for general engineering, agricultural, and machinery assembly, A4 where the pin faces outdoor, washdown, marine, or de-icing salt exposure, since surface pitting on the grooved ridges reduces the very grip the design depends on. Diameter should match the drilled hole size specified for the application, and length should fully engage the intended hole depth without excessive protrusion at either end.

FAQs
How does DIN 1473 differ from DIN 1471?
Both are grooved along the full length, but DIN 1471 uses a tapered groove profile of varying depth, while DIN 1473 uses a parallel groove profile of constant depth, affecting how evenly the pin's grip is distributed along its length.

Can DIN 1473 pins be inserted from either end?
Chamfers are typically present at both ends with a constant groove depth, which can make orientation less critical than with a tapered pin, but this should be confirmed against the specific product rather than assumed.

Is DIN 1473 a good choice for a pin that will be removed and refitted regularly?
The even grip along its length means wear from repeated insertion is spread more evenly than on a taper profile, but as with all grooved pins, retention still reduces gradually with each reinsertion, so frequent servicing points are better served by a spring pin than by any grooved type.
