中国Press-In
Press-In Inserts are designed to be pressed into a straight hole without melting the plastic prior to installation. Ideal for use in softer plastics, the helical knurls of the Press-In Inserts are used to provide both torque and pull-out resistance and to ensure good plastic flow as the Insert rotates into the hole. Installation torque to achieve sufficient tension between the threads is not a problem in that the helical knurls are designed so that the direction of the installation torque will have the tendency to drive the Insert into the hole — which of course is not possible — as the threaded joint is tightened. A pilot only slightly smaller than the hole and of sufficient length is designed to assure straight insertion into the hole. Press-In Inserts offer rapid installation with no specialized equipment and achieve good overall joint performance.
If installation equipment is required, SPIROL also offers a standard comprehensive line of Insert Installation Equipment from manual to fully automatic modules, with or without out fixturing, to support your Threaded Insert assembly requirements.

Press-In Threaded Inserts Product Listing
Press-In Insert
The Series 50 Press-In Insert is provided with generous pilots on each end to facilitate installation into the hole. Given that the Series 50 is a symmetrical Insert, orientation of the Insert prior to installation is not required. Series 50 Press-In Inserts are available in both metric and inch thread sizes ranging from M2 (2-56) up to M8 (5/16-18)
Headed Press-In Insert
Series 51 Headed Press-In Insert is the headed version of SPIROL's Series 50 Insert. The Series 51 Press-In Insert is provided with a generous pilot on the end opposite the head to facilitate installation into the hole. The addition of the head provides additional bearing surface for the screw, and also makes it suitable for pull-through applications where high tensile (pull-out) force is required. Series 51 headed Press-In Inserts are available in metric thread sizes ranging from M2 to M8 and unified thread sizes ranging from 2-56 to 5/16-18.
