STANDARD SPRING PINS. Standard spring pins are manufactured to ASME B18. Standard finishes for high carbon steel spring pins are either light oil or zinc. Standard stainless steel spring pins are passivated.
Is standard for dowel pins?
The most common standard inch or imperial sized precision dowel pin is made to the ASME ANSI B18. 8.2 spec and has a diameter tolerance of -0.00 / +0.0002 and length tolerance of +/-0.010. For example, a ¼” (0.25) diameter standard dowel pin will have a diameter between 0.2500–0.2502″.

Are roll pins and spring pins the same?
A spring pin is an unthreaded mechanical fastener that expands to securely fit in a hole. Spring pins, also known as roll pins, are designed to be inserted into a hole that has a smaller diameter than the pin. In this case, a pin that's longer than the diameter of the shaft must be used.
What is the recommended hole size for a .312 8 diameter spring pin?
They are crafted from alloy steel, carbon steel, and stainless steel featuring spring like elastic properties. Spring pins are used as locking devices, positioning points, anti‑chafing surfaces, shafts, or sleeves for wiring.Apr 8, 2021

What is a spring dowel pin?
Spring dowel pins are slotted pin made from high carbon spring steel (EN-42J) material having 44- 51 HRC. They can also be manufactured from stainless steel material i.e. SS- 304, SS- 420, SS- 316 etc. Spring Dowel pin is accurately made to diameter greater than the drilled hole into which it is pressed.
Are roll pins strong?
Roll pin is tight and the ones I've used are fairly soft compared to a grade 8. Grade 8 bolts are strong at holding clamping loads, they don't always work great as a shear type pin.Feb 2, 2015
How are spring pins measured?
Slide the jaws open inside of the divot to measure the diameter. Hold the strap and the gauge steady and use the index finger of your hand holding the gauge to slowly slide the jaws open. Continue opening them until they're fully flush against the small divot of the strap to find the diameter of your spring pin.
How are roll pins sized?
The recommendation is not to go smaller, the hole sizes vary with the size of pin from 0.003" up to 0.014" as the diameter increases. They are also referred to as "American National Standard Spring Pins".
