Straight & Dowel Solid Pins

SPIROL's DP100 Straight Pins have smooth outer diameters with no retention features such as knurls or barbs. When used as a press-fit pin, the DP100 Straight Pin is pressed into a hole sized slightly smaller than the diameter of the pin. Interference between the pin and the hole must be limited in order to keep insertion forces within practical limits and to prevent damage to the pin or hole during installation. SPIROL's DP100 Straight Pins are suitable for press fit in host materials that can withstand compression in the order of 0.05mm – 0.08mm (.002” – .003”). The actual recommended hole size for a press-fit depends on the actual host material. It is for this reason that SPIROL Engineering should be consulted for the recommended hole size when DP100 Straight Pins are intended to be press-fit into an assembly. Straight Pins are a great option for applications that do not require the tight tolerances of Machined Solid Pins or Ground Solid Dowels. SPIROL Series DP100 Straight Pin consists of metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4).

SPIROL's FH100 Headed Straight Pin has the same body style as the DP100 Straight Pin, with the addition of a head. A Headed Pin is typically used to provide a positive stop or to retain a thin component to a thicker component within an assembly. FH100 Headed Straight Pins have a flat head, however they are available to order with a round head (RH100) to meet specific application requirements. Similar to the SPIROL Series DP100 Straight Pin offering, SPIROL's Series FH100 Headed Straight Pin is available in metric diameters ranging from Ø2mm to Ø6mm and inch diameters ranging from Ø.078" (5/64) to Ø.250" (1/4).
