1.Features Rust and corrosion resistance: made of stainless steel, it has good rust and corrosion resistance, can be used for a long time in harsh environments, not easy to rust or damage, and has a long service life, which reduces the frequency of replacement and maintenance costs. High strength load-bearing: stainless steel tensile strength ¡Ý500MPa, meets the fixing needs of fishing bracket, storage box and other heavy-duty accessories. Convenient and efficient installation: the track nut can be slid along the track to adjust the position and can be locked without tools. Low maintenance cost: Stainless steel fasteners do not need to be replaced for 3~5 years, reducing the maintenance frequency. 2.Specifications Screws: diameter 6mm, thread length 20mm, total length 24.5mm. Nuts: length 29mm, width 13mm, thickness 3mm. 3.Package contains 4 screws and 4 nuts. 4.Tips Prohibit excessive modification: the core structure of the hull (such as buoyancy chamber, keel) can not be arbitrarily punched to avoid affecting the safety. Material Matching: Stainless steel screws in contact with aluminium alloy hull need to use insulating gaskets (such as plastic/rubber gaskets) to prevent galvanic corrosion.
