1 SI THRDD INSRTS FOR PLSTIS BULLTIN SI 410

2 SI THRDD INSRTS FOR PLSTIS SI inserts are typically specified in applications where strong, durable metal threads are required in plastic material, especially where frequent assembly and disassembly of the unit for service or repair is necessary. pplications for SI products include: computers and terminal boards, automotive, electronic equipment, business machines, aerospace, communications equipment and instrument cases. SI inserts are available in brass, stainless steel and aluminum. SI inserts are available in a large variety of ultrasonic / heat staking, molded-in or press-in types. SI inserts meet the strictest quality guidelines which are maintained through in-process audits. ULTRSONI / HT STKING INSRTS Ultrasonic - Installed by pressing the insert into the mounting hole with ultrasonic insertion equipment while simultaneously applying a high frequency vibration. Frictional heat caused by the vibration melts the plastic surrounding the insert allowing easy insertion. When the vibration ceases, the plastic solidifies, locking the insert permanently in place. Heat Staking - Installed by pressing the insert into the mounting hole with a thermal press to melt the plastic surrounding the insert. MOLDD-IN INSRTS Installed during the molding process, the inserts are located in the mold cavity by core pins. When the mold opens, the core pins are withdrawn leaving the inserts permanently encapsulated in the plastic section with only the threads exposed. Installing the inserts during the molding process eliminates the need for secondary steps or installation equipment. PRSS-IN INSRTS Installed by simply pressing the inserts into pre-molded or drilled holes. Installation is accomplished using any standard press at any time during the production process. liminates the need for molding-in inserts. liminates the need for heat or ultrasonic equipment. SI-2

18 USTOM DSIGNS FOR SPIL PPLITIONS If you can not find a standard product in this catalog to meet your requirements, our pplication ngineering Department will assist you to design a custom fastener to satisfy your requirements. Below are a few examples of custom insert designs. SNP-TOP ULTRSONI INSRTS Designed for ultrasonic installation allowing a spring action to hold a P board securely without screws or other threaded hardware. SI ultrasonic SNP-TOP inserts are available in lengths from 1/4 to 1 / 6.35 to 25.4 mm spacing. These inserts can be provided in aluminum, brass, and stainless steel and are designed for ultrasonic installation into cored or drilled holes. THIN SHT STUDS Provide external threads in material as thin as.125 / mm. SI studs are available in lengths from 1/4 to 3/4 / 6.35 to mm in thread sizes #4-40 to 1/4-20 / M3 to M6. These inserts can be provided in aluminum, brass, steel and stainless steel and can be pressed into pre-molded or drilled holes. ULTRSONI STUDS Tapered body provides easy insertion in pre-molded or drilled holes. They are available in lengths from 1/4 to 3/4 / 6.35 to mm in thread sizes #2-56 to 1/4-20 / M2 to M6. These inserts can be provided in aluminum, brass, steel and stainless steel. SLF-LOKING ULTRSONI INSRTS The self-locking feature prevents screw loosening and is advantageous in applications where vibration is present. They are available in thread sizes #2-56 to 1/4-20 / M2 to M6 and are designed for ultrasonic installation into straight or tapered holes. THRMOPLSTI INSRTS llows for mounting a component on the external thread. They are available in lengths from 3/16 to 1 / 4.76 to 25.4 mm. sizes #4-40 to 1/4-20 / M3 to M6. SI thermoplastic inserts can be provided in aluminum, brass, steel and stainless steel and can be pressed into pre-molded or drilled holes. SI-18

19 HOL PRPRTION GUIDLINS s a general rule, the wall thickness should be 1/2 to 1 times the insert outside diameter. If the insert application is in a circular boss, the boss diameter should be 2 times the insert diameter. Thinner walls and bosses may be used but will affect performance. Boss Dia. 2 x insert dia. Insert Dia. Wall Thickness PULLOUT TORQU OUT Pullout is the force required to pull the insert from the sheet. Torque-out is the torque required to turn the fastener in the parent material after installation without inducing clamp load on the fastener. SI-19
