Custom Eccentric Shafts In 431 Stainless Steel Material

Custom Eccentric Shafts In 431 Material
We supply our customer these custom eccentric shafts on a revolving blanket purchase order basis, typically at 350 pieces required annually.  431 material per AMS 5628 material was used to manufacture these tricky parts, with heat treat, dicronite finish per AMS 2530 not to exceed .0002" in thickness.  Dimensional tolerances were very stringent on these parts, at +/- .0002" on many of the cross section diameters along the shaft.  The hex socket drive was broached with engagement to be at .175" minimum and overall drill depth not to exceed .200".

Custom Modified Socket Cap Screws - 2-56 X .745 With Machined Groove

Custom Modified Socket Cap Screws - 2-56 X .745 With Machined Groove
In getting these custom modified socket cap screws made we started with standard off the shelf 2-56 X 3/4" socket cap screws in 18-8 stainless steel material - our customer required the length to be cut and chamfered down to .745" and a groove to be added 1/8" from the point.  The groove measured .052" to .054" in diameter and .061 to .071" in length.  Both modifications were relatively simple and we were able to get the parts ready within 2-3 weeks from purchase order placement.

Custom Painted Rivets - 1/8 Blind Rivets In Color Matched Green

Custom Painted Rivets - 1/8 Blind Rivets In Color Matched Green
Our customer requested us to match the color of the roofing material for these custom painted rivets.  The color is a shade of dark green and the customer specifically wanted us to paint both sides of the rivet - this is very unusual, with only the visible side typically painted since the blind side is never visible after the rivets are installed.  This dual application required 2 separate paint applications to accomplish the end result, with a strip process completed prior to paint to ensure there was no wax present on the surface.  Any wax present on the surface would result in flaking or peeling of the paint within days of the completed process.
