Unfortunately, this method only has limited durability and has a minimum amount of assembly repeatability.2 FIGURE 19 - Mechanical Fasteners Design Guidlines Potential high stress due to wedging action of screw head Potential high stress due to wedging action of screw head Poor DesignsPoor Designs Preferred DesignsPreferred Designs Planned gap between added bosses prevents excessive bending of hosing as bosses touch and go into compression Planned gap between added bosses prevents excessive bending of hosing as bosses touch and go into compression Alternative recessed head design avoids potentially dangerous wedging action Alternative recessed head design avoids potentially dangerous wedging action Truss or Round Head ScrewTruss or Round Head Screw Potential high bending stress as bolt is tightened Potential high bending stress as bolt is tightened Flat-head Screw Standard Screw Plastic Part Metal Sub-frame Shoulder Screw Plastic Part Metal Casting FIGURE 20 - Mechanical fasteners design guidelines F= π × µ × DShaft 1engage × σH W I = D – 0.373 = 0.0002" σH = 1 × W DShaft W + v E( ) σH = = 200psi 0.002 × 1.998 0.375 1.998 + 0.4 450000( ) W = = 1.998 1 – 0.375 0.650( )2 1 + 0.375 0.650( )2 W = DShaft ODHub 1 – ( )2 DShaft ODHub ( )2 1 + FIGURE 16 - Interference fit variable F= π × µ × DShaft 1engage × σH W I = D – 0.373 = 0.0002" σH = 1 × W DShaft W + v E( ) σH = = 200psi 0.002 × 1.998 0.375 1.998 + 0.4 450000( ) W = = 1.998 1 – 0.375 0.650( )2 1 + 0.375 0.650( )2 W = DShaft ODHub 1 – ( )2 DShaft ODHub ( )2 1 + FIGURE 17 - Geometry factor variable F= π × µ × DShaft 1engage × σH W I = D – 0.373 = 0.0002" σH = 1 × W DShaft W + v E( ) σH = = 200psi 0.002 × 1.998 0.375 1.998 + 0.4 450000( ) W = = 1.998 1 – 0.375 0.650( )2 1 + 0.375 0.650( )2 W = DShaft ODHub 1 – ( )2 DShaft ODHub ( )2 1 + FIGURE 18 - Hoop stress equation F= π × µ × DShaft 1engage × σH W I = D – 0.373 = 0.0002" σH = 1 × W DShaft W + v E( ) σH = = 200psi 0.002 × 1.998 0.375 1.998 + 0.4 450000( ) W = = 1.998 1 – 0.375 0.650( )2 1 + 0.375 0.650( )2 W = DShaft ODHub 1 – ( )2 DShaft ODHub ( )2 1 + FIGURE 19 - Press fit pull-out force .400 .500 .375 .373 .650 FIGURE 15 - Press fit example Design Guide 13 ADHESIVE TYPES A chart containing the various specific adhesive types, with advantages and disadvantages of both can be seen in the appendix.

To get an accurate reading you must have a flat part surface, as well as sufficient part thickness to prevent the support surface from affecting the result. If shrinkage is uneven, a part meant to lay flat can bend or warp.
