USAGE GUIDELINES
– The pilot hole size is very important to achieve a proper installation. Make trials using the guidelines in the product datasheets before mass production. The hole size would be dependent upon the base material strength, base material thickness, pull out strength and ease of installation required.
– Do not overtighten. Use the correct tightening Torque as recommended. See the product datasheets for information. Usage of Torque control drivers is suggested.
– Do NOT use the screws to compensate for any alignment defects by applying more force than required. This will cause un-stability of the connection and unpredictable failure.
– Use the correct countersink tool for CSK screws to achieve a flush fixing.
– Use a good quality drive bit to avoid excessive play and Cam out problems.
