Is a roll pin the same as a tension pin?
A spring pin (also called tension pin or roll pin) is a mechanical fastener that secures the position of two or more parts of a machine relative to each other. Spring pins have a body diameter which is larger than the hole diameter, and a chamfer on either one or both ends to facilitate starting the pin into the hole.
What is a coiled roll pin?
Slotted & Coiled Spring or hollow pins are economical, universally used shear-type fasteners that are self-locking. They’re manufactured to an oversize dimension so that when the pin is inserted into a hole, radial forces are exerted that hold the spring pin in place.
What is the difference between a roll pin and a spring pin?
Also known as a roll pin, a spring pin is a type of fastener that’s used to join two or more machine components. They are called “spring pins” because they contain a spring that expands upon insertion.
How hard are roll pins?
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.
What is the recommended hole size for a .312 8 diameter spring pin?

What is a spring pin made of?
steel
Spring pins, commonly known as slotted pins, rolled pins, or tension pins, are hollow, cylindrical tube‑style press fit fasteners with chamfered ends. They are crafted from alloy steel, carbon steel, and stainless steel featuring spring like elastic properties.
Whats the difference between a spring pin and a roll pin?
Also known as a roll pin, a spring pin is a type of fastener that’s used to join two or more machine components. They are called “spring pins” because they contain a spring that expands upon insertion. What’s perplexing about spring pins, however, is their size.
What is spring dowel pin?
Spring dowel pins are slotted pin made from high carbon spring steel (EN-42J) material having 44- 51 HRC. Spring Dowel pin is accurately made to diameter greater than the drilled hole into which it is pressed.
Are roll pins hardened steel?
Roll pins (slotted steel springs, slotted spring pins) are made of rolled steel or another, similar metal and then rolled into a cylindrical shape. These headless, hollow fasteners have a slot that runs longitudinally down the length of the pin.
