Where applicable, published specifications covering a particular fastener will be referenced in the section of this booklet dealing with that fastener. When referring to standards and specifications, we will use only the well-known initials of the above MECHANICAL FASTENERS KEYS Keys are used to prevent relative motion between a shaft and the connected member through which a torque is being transmitted. Even though gears, pulleys, etc are assembled with an interference fit, it is desirable to use a key designed to transmit the full torque. Common types of Keys: 1.

Aluminum Fasteners. They are the lightweight fasteners and are used where weight is constrained and can be alloyed into many other materials to increase its strength. Acceptance to hot and cold temperatures is the USP of these fasteners. It is naturally corrosion resistance and non-magnetic.

Mechanical fasteners can drive up costs, limit options for materials, and cause fatigue, metal distortion or tearing. Mechanical Properties of Internally Threaded Fasteners (1): Galvanize coating refers to nuts that have been plated with a plating or coating of sufficient thickness to require over tapping of the nut to provide assembly: for example hot -dip or mechanical galvanizing. SAE J995 does not address proof strength reduction where overtapping is required.
