A security Torx L-key and fastener with holes for a safety pin to hinder disassembly with an ordinary Torx key. A Torx T8 screw head on a hard disk drive.. 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.
SMA connectors are rated for up to 500 mating cycles, [8] but to achieve this it is necessary to properly torque the connector when making the connection. A 5 ⁄ 16 inch torque wrench is required for this, set to 3–5 in·lbf (0.3 to 0.6 N·m ) for brass, and 7–10 in·lbf (0.8 to 1.1 N·m) for stainless steel connectors.
A pentagon screw drive uses five-sided fastener heads, and the fastener is known as a penta screw or penta bolt. It is designed to be intrinsically incompatible with many tools. Since five is an odd number, it cannot be turned by open-end or adjustable wrenches, which have parallel faces (and thus require a fastener with an even number of sides).
Most torque screwdrivers allow the torque to be set to any value within a range. All have a torque-limiting clutch that disengages once the preset torque has been reached. Torque screwdrivers can exert torques from 0.04 N⋅m to at least 27 N⋅m. [1] Although no single tool covers the entire range, low-, mid-, and high-torque ranges are available.
A click torque wrench. A torque wrench is a tool used to apply a specific torque to a fastener such as a nut, bolt, or lag screw.It is usually in the form of a socket wrench with an indicating scale, or an internal mechanism which will indicate (as by 'clicking', a specific movement of the tool handle in relation to the tool head) when a specified (adjustable) torque value has been reached ...
Torque forms part of the basic specification of an engine: the power output of an engine is expressed as its torque multiplied by the angular speed of the drive shaft. Internal-combustion engines produce useful torque only over a limited range of rotational speeds (typically from around 1,000–6,000 rpm for a small car).
However, small set screws without flats are prone to spinning and galling if overloaded. The use of keys and keyways instead of, or in combination with, set screws is common for applications requiring high torque resistance or transmission. Splines offer yet more strength. For longer life, set screws are usually made of alloy steel and case ...
