To satisfy the demand for fasteners with a black finish, Lancaster Fastener Co Ltd is now equipped to have any of its zinc plated and stainless steel fasteners finished black within a very short time frame.

Building on its existing stocked range of fasteners with a black finish, the UK company’s intention is to offer a reliable and consistent supply of product ranges that are often regarded as problematic and time-consuming for fastener distributors to source.

“We’re aware that many distributors have the need to have zinc plated and stainless steel fasteners from our range finished black,” explains Sam Wilson, managing director at Lancaster Fastener. “We have the processes and logistics already established with a reputable plating company to facilitate this need – so we decided to offer our finishing service across our entire product portfolio.”

A decorative dip-spin black top coat with enhanced corrosion resistance and low coating thickness can be applied to Lancaster’s existing zinc plated and stainless steel stock. The thin layer application makes it suitable for small fasteners where tolerances are limited and there is no ‘build-up’ in the screw’s recess or threads. The surface treatment is free of hazardous substances and conforms to EU guidelines relating to the End of Life Vehicle Directive (2000/53/EC). Also, because the finish is a top coat, no hydrogen embrittlement occurs in the application of the black finish.

Lancaster’s independently commissioned corrosion resistance tests of the black finish when applied to its products achieved a minimum of 150 hours to white rust.
