Sussex Wire Launches New Medical Fastener


Easton PA (September 30, 2015) - Sussex Wire announced today the commercial availability of a new stainless steel insert screw designed to improve adjustment control, mitigate contamination, and increase component part geometry and tolerance, while improving manufacturing volume to over 100 million parts/year. The stainless steel precision drug delivery control insert screw measures just 0.320” long with a head diameter of 0.187” +/- 0.005” and includes precision head grooves for gripping a rubber over-mold. #3-48 micro threads are roll-formed in the part after heading.

Sussex Wire designed the net shape micro screw to produce no scrap, and in the process, developed machine automation and sensor controls to ensure six sigma yield while eliminating costly inspection by the customer. Sussex Wire’s proprietary manufacturing cell control system eliminated the pre-existing condition of malformed and contaminated parts reaching the customer.

The new part incorporates all of the benefits of cold forming, including high part throughput rates, significant cost economy, and 100% net shape, resulting in zero scrap or material waste. In addition, the finished part is clean and burr-free after forming, thus eliminating expensive and time consuming secondary operations. One of the major advantages compared to a similar part manufactured by machining is strength; cold forming and thread rolling actually increase material hardness over the original material tensile, rather than weaken it as machining does, substantially improving durability and performance reliability.
