Custom 316 Stainless Steel Shoulder Screws - 4-40 X 1

Custom 316 Stainless Steel Shoulder Screws - 4-40 X 1

We had a small batch of these custom 316 stainless steel shoulder screws produced domestically for our electronics OEM customer. Partial 4-40 thread was incorporated, with a machined shoulder incorporated per our customer specifications. Due to the smaller quantity involved the hex socket drive was broached rather than cold headed - you can see the slight rough nature of the drive when zooming into the photo. The lead time for these parts was relatively fast, with 2-3 weeks for production.
