The wall thickness (W) for ribs and bosses should be 75% of the nominal wall (.75W). The outside round should be the inside radius plus wall thickness (IR + W). 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 Metal Casting FIGURE 20 - Mechanical fasteners design guidelines σH = DShaft W = DShaft DShaft 1 + FIGURE 16 - Interference fit variable σH = DShaft W = DShaft DShaft 1 + FIGURE 17 - Geometry factor variable σH = DShaft W = DShaft DShaft 1 + FIGURE 18 - Hoop stress equation σH = DShaft W = DShaft DShaft 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.
