TIMCO Polymer Headed Pins in mahogany are A4 (316) stainless steel pins with a small, colour-matched polymer head, made for pinning coated trims, beading and roofline detail where the fixing must not show and needs to last outdoors. The stainless shank carries a corrosion rating of 5 for coastal and industrial air, and the UV stable head holds its colour through the weather. They run on a fine 2.1mm shank with a 6.4mm head in 25mm, 30mm and 40mm lengths. The light-duty partner to polymer headed nails, and a tidy choice on oak and cedar.
