CATALOG 14 E P : 1-800-265-8772 F : 1-888-252-6380 www. .com Inch Pouce Rivet Installation Tools E41 Nylon Poly Drive Rivet Tolerances and Quality of Injection Molded Nylon Screws Insertion Tool This tough, lightweight drive rivet insertion tool makes the assembly of nylon drive rivets even more economical! This tool provides faster assembly and more accurate placement and positioning in those hard-to-reach areas. A large plunger head and easy-grip handle reduces operator fatique. The rivets do not have to be pre-driven! The rivet is loaded into the tool and then inserted into the prepared hole. Quick pressure on the plunger by the operator frees the pin and expands the rivet in the assembly. Three sizes are available colour coded to cover all standard drive rivets. SPAENAUR No. Rivet Pin Size Colour 876-854 .075" (1.9 mm) Red 876-855 .125" (3.1 mm) Yellow 876-856 .150" (3.8 mm) Green 18 Jan 2018 PKG QTY. 1 Micro Plastics' molded nylon components are accurately molded of Type 6/6 Nylon. They are tough, resistant to corrosion, light weight, and good electrical insulators. Nylon components conform to irregular surfaces, provide vibration dampening, and offer an inexpensive alternative to more expensive metal parts. Molded threads approximate UNC/UNF 2A and 2B. Metric approximate 6g/6H. Tolerances are held to Industrial Fasteners Institute Standards for inch and metric screws. However, it is often more sensible to try samples or small order quantities before changing from one product to another. Plastic molding has varying degrees of quality. It often involves small amounts of flash, knockout pin marks, gates, sinks, and other slight imperfections. Screws and bolts are gated on the threaded end. It is possible for the gate to leave an extra projection of up to .025". Nylon screws have been available for many years commercially. They are either machined on a screw machine or injection molded. The machined parts are made from extruded nylon rod stock and can be held to relatively close tolerances during the machining process. Nylon, however, has the unfortunate property of absorbing moisture from its environment which causes significant changes in its dimensions. So even though parts may have been accurately machined, a moist atmosphere can cause fit problems. Conversely, parts that have been moisture conditioned "lose" moisture causing dimensional problems. If the overall length of a screw grows, it obviously affects the threads per inch thus causing a tight fit. Changes in the moisture content can also have an effect on the outside diameter, pitch diameter, and the root diameter.
