88 THE DISTRIBUTOR’S

88 THE DISTRIBUTOR’S LINK GROWERMETAL SRL Via Nazionale 3, 23885 Calco (LC), Italy TEL +39 039 9535300 FAX +39 039 9535400 EMAIL info@growermetal.it WEB www.growermetal.it GROWERMETAL: INNOVATING INTO THE FUTURE Growermetal is an experienced manufacturer of washers in Europe, based in Calco (Northern Italy). The production range covers more than 4000 items produced according to the most common international standards like ISO, ASME or DIN. The number of customized products according to drawing, currently about 2000 items, is continuously increasing thanks to the technical knowhow acquired through the last 70 years. The company is present not only on the Italian market but also in Europe and in other regions such as America, Middle East, China and other countries of the Far East. Growermetal’s sales are approximately 40% to distributors, most in the fastener business and 60% to first or second tier end users, who assemble the washer on their products to sell directly to end users. Last year the R&D department of Growermetal started a new project and studied more than 400 types of geometry by using of simulation software and numerous laboratory tests. The goal of all involved technicians was to create a safety washer with innovative features for outstanding performances, which nowadays is a real challenge considering the huge, existing market for fixing components worldwide. At the Fastener Fair Stuttgart 2019 (Germany), which is the most important showcase for fastener and fixing technology in Europe, the company launched its new safety washer brand Grower TenKeep® and won the 3rd place in the Route to Fastener Innovation Competition. The innovation compared to other safety washers on the market is that Grower TenKeep® safety washers have the two surfaces with knurls of different geometry, specially designed to ensure maximum performance against unscrewing of the bolted joints even in the presence of extreme vibrations and dynamic loads. Side A of the washer on the head of the screw/ nut side slides against the surface of the underhead of the screw/nut when tightening the bolted joint. The advanced serration geometry of this side instead counteracts very efficiently the loosening of the bolted joint connection. The hole on side A has a chamfer on the hole, which provides the dual function of avoiding any interference with the radius under the screw head and allowing the user to orientate the washer correctly.
