Camcar eventually became part of Textron Fastening Systems in the 1990s. In 2006 Textron Fastening Systems was sold to Platinum Equities, LLC, of Beverly Hills, California. They renamed the company Acument Global Technologies, which as of 2010 includes Avdel, Camcar, Ring Screw, and others. In 2014, Acument was sold from Platinum Equity to Fontana Gruppo.

Allen™ screws and wrenches are not the be-all-end-all in the world of fasteners and tools. Some complaints focus on the tool size being too small to allow for one to apply sufficient torque in all cases. Also, inferior materials used in the manufacturing of either the wrench or the screw can render them easy to damage in spite of the increased number of pressure points. But they are still popular more than 100 years after William G. Allen™ filed for his patent and will likely be here to stay for the foreseeable future. Summary

Torx (pronounced / t ɔːr k s/) is a trademark for a type of screw drive characterized by a 6-point star-shaped pattern, developed in 1967 [1] by Camcar Textron. [a] A popular generic name for the drive is star, as in star screwdriver or star bits. The official generic name, standardized by the International Organization for Standardization as ISO 10664, is hexalobular internal. [2] This is sometimes abbreviated in databases and catalogs as 6lobe (starting with the numeral 6, not the capital letter G). Torx Plus, Torx Paralobe and Torx ttap are improved head profiles. [3] Range of access – Allen™ wrenches that feature a hex ball end can allow fasteners to be accessed from angles other than directly in the same plane as the fastener. This can simplify assembly & disassembly in close quarter conditions. A successor to the original Torx design was Torx Plus, introduced in 1990. This design made improvements on the original which enabled higher torque to be applied while minimising wear.

AudiTorx is a tamper-proof fastener where a convex and smooth fastener head is topped with a break-away Torx drive that snaps off when the engineered torque is reached, leaving a rivet-like bolt head that cannot be easily removed. The main application for these fasteners is in the railroad industry. [29] External (inverted) Torx [ edit ] External Torx driver
