Dowel Pins & Spring Pins
Solid dowel pins and slotted spring pins, quoted on diameter, length, tolerance and material. They are not substitutes: a dowel pin locates two parts to a tolerance, and a spring pin holds by interference, and putting one where the drawing calls for the other changes how the joint behaves.

What decides the price
In order of impactA dowel pin is a locating element. A spring pin is a retaining element. Different jobs, different fits.
Dowel pins are supplied to a tolerance class and the hole has to match it. A pin ordered without the class is a pin that may or may not press in.
Hardened dowels resist shear; unhardened ones deform. Spring pins are usually supplied in spring steel and that is stated.
Worth checking before you order
It holds, and it allows movement. If the drawing wants location, it wants a dowel.
The pin galls and the bore is damaged. Ream to the tolerance class the pin was made to.

Questions
Is ISO 8752 the standard you supply to?+
For slotted spring pins, yes, and we state it on the part number. Heavy-duty series is a different standard.
Can you supply pins to a tolerance class?+
Yes. Tell us the class and the hole size on the drawing.
Send the specification, not the product name.
Grade, size, thread standard and coating are what a quote is built from. A product name alone produces a price that changes twice before the order.
