Spirol Bissell, the distribution division of Spirol Industries Ltd, now offers a comprehensive range of knurl pins. These are ideal for making fastenings in soft materials and thin cross sections where their multi-crested design evenly distributes the retention force. They are available in two types: straight and helical and with either full-length or partial length knurls. Offered in diameters from 1.5mm to 6mm, Spirol knurled pins can be specified in low carbon steel or nickel stainless steel 300 series. Standard finishes include plain, oiled, zinc plated or phosphate coated. Imperial sizes are also available. All products are produced under ISO 9000 and QS 9000 certifications. Spirol Bissell has been established following the acquisition by Spirol Industries of George Bissell. It serves the distributor market and smaller customers throughout Europe.
