SPIROL's Series LP500 Latch Pins for Plastics were designed specifically for use in plastic latch applications. Designed with a barb located under the head, the remaining length of the LP500 Latch Pin is smooth to allow the pin to easily align and freely install through all of the holes with a plastic assembly. Once the barb under the head makes contact with the final hole, the LP500 Latch Pin is securely locked in place. Once fully installed, the assembly will pivot freely around the smooth end of the stationary pin. The head prevents the LP500 Latch Pin from being over-installed, and enables the pin to be mechanically oriented for automatic installation. SPIROL's LP500 Latch Pins for Plastics are manufactured from lightweight, lead free aluminum and are available in three standard diameters: 3mm, 4mm and 5mm in lengths to meet specific application requirements.
