1/4 X 1/4 Alloy Dowel Pin to Print

Dowel pin specials are a common component of our special fastener offering to manufacturers and this particular part is a 1/4 X 1/4 dowel pin made using alloy steel to print.  Unlike many other fastener parts dowel pins are often more difficult to produce when tight tolerances are required, typically necessitating domestic US manufacturing of the parts.  This is particularly pertinent when working with miniature custom pins.

Invar 36 1/4-20 X 1-1/4 Socket Cap Screws

We were presented with the challenge of having custom 12 socket cap screws made out of Invar 36 material to a provided print in a relatively short period of time, which is essentially a 36% nickel iron alloy material, with matching finished hex nuts.  This material is typically used for applications where dimensional properties must be maintained across a broad range of temperatures.  We were able to have the parts produced and delivered within 3 weeks of order date.  While in this specific case no certifications were required, various documentation would have been available to the customer if requested and required.
