Warren/Fenner: Failure to take into consideration the compression forces and outward forces generated when using locking devices. The mounted component must have sufficient wall thickness to withstand the outward forces or it will burst. Likewise when mounting on hollow-shaft or tubular applications. Inadequate wall thickness Air results in Tpol the hollow shaft or tube being compressed and distorted. Many manufacturers publish a Screwdrivers formula or table that lets designers calculate the required Air wall thickness.Vic/Rimtec: Having too much clearance between the shaft and hub is often a problem; you can''t clamp enough to transmit rated torque. Overtightening the screws is also common, causing tapers to lock when they''re supposed to disassemble. This is where locking devices with push-off screws come in handy.
