Mac torque tool for 18 wheeler drivers#
Originally, with the introduction of electric power tools, the design of screws was developed to encourage cam-out (the disengagement or slippage of a driver from a fastener head) at high torque levels, this was because high-torque drivers could damage fasteners and housings when over-tightened, and disengagement from the driver was intentionally implemented as a safety feature.
In many cases, unique fastener attributes can allow for innovations in product design and security, but in some cases, customers argue that standard components would probably have sufficed - This was famously seen when technology giant Apple launched its patented ‘pentalobe’ fasteners, which came under heavy criticism for being unnecessarily restrictive back in 2009. Company-specific designsĪnyone who has ever put together flatpack furniture will be familiar with the weird and wonderful screw types which companies invent for their products.
Arguably, the more hard-to-find a security driver is, the more effective it is at its job. In total contrast with almost all other drive types, security drives are interesting in that their appeal lies in the fact that they are deliberately inconvenient to operate. A fastener that cannot be loosened without special tooling is inherently resistant to tampering, and Security Screws are specifically designed to be difficult to operate without the correct tooling. One advantage for the use of unusual drive types is the added security that an uncommon drive type can provide. An engineer's toolkit is incomplete without an abundance of screwdrivers and drive bits for all manner of different screw drives, so why is there not just one uniform type? Whether they were developed at different times, for different purposes, or just by different companies, there are numerous reasons for the myriad of fastener drive types on offer. Why do we need so many drive types?įasteners are available in innumerable different shapes and sizes, and one of the most common permutations is drive type. What is the Best Screw Drive? Phillips, Flat Head, Pozi and Torx.
