API Spec 7K (Drilling and Well Servicing Equipment) was last updated in 2010 in its Fifth Edition. It provides general principles and specifies requirements for design, manufacture, and testing of new drilling and well-servicing equipment and of replacement primary load-carrying components.

This specification is applicable to the following equipment:

• rotary tables

• rotary bushings

• standard rotary slips designed for use in standard rotary bowls with a 33.333 cm/m (4 in./ft) API taper

• nonstandard rotary slips without a taper of 33.333 cm/m (4 in./ft) for use in manual spiders as described in Item i)

• high-pressure mud and cement hoses

• piston mud-pump components

• drawworks components

• manual spiders that use standard rotary slips as described in Item c) that are not capable for use as elevators and are installed on or above the master bushing/rotary table

• manual spiders that use nonstandard rotary slips not having a taper of 33.333 cm/m (4 in./ft) not capable of use as elevators, and installed on or above the master bushing/rotary table

• spring, pneumatic, or hydraulic spiders with integral slips not capable for use as elevators and are installed on or above the master bushing/rotary table

• spring, pneumatic, or hydraulic spiders with integral slips not capable for use as elevators and are installed in, or partly in, the rotary table

• manual tongs

• safety clamps not used as hoisting devices

• power tongs, including spinning wrenches

• blowout preventer (BOP) handling systems

• pressure-relieving devices for high-pressure drilling fluid circulating systems

• snub-lines for manual and power tongs
