Socket wrench set saTra RF-4122-5 — 12-piece 1/2" drive, 6-point sockets 10–24 mm

saTra RF-4122-5 is a 12-piece socket wrench set with a 1/2" drive and 6-point sockets in metric sizes from 10 to 24 mm. The compact kit supplies a ratchet handle and a selection of sockets intended for manual tightening and loosening of hexagonal bolts and nuts. This set is designed for general automotive repair, machinery maintenance and workshop tasks where common metric fasteners are used.

Advantages

The 1/2" drive ratchet provides increased torque compared with smaller drives while preserving comfortable hand operation. Six-point sockets fit hex fasteners securely to reduce rounding and slipping. The set’s size range covers common medium-to-large metric fasteners, allowing work on engine components, chassis fittings and industrial machinery. The compact assortment simplifies storage and transport between job sites or within a workshop.

How to use

Select the socket that matches the fastener size and attach it securely to the 1/2" drive ratchet. Place the socket over the fastener head so that the six contact points align with the hexagon shape. Use the ratchet handle to apply torque in the required direction; switch the ratchet’s direction lever when changing between tightening and loosening. Apply steady, controlled force and avoid using cheater bars or excessive impact to prevent damage to the tool or fastener.

Usage recommendations

For reliable service life, keep sockets and the ratchet clean and dry after use, periodically inspect for wear or rounding, and store the set in a dry place. Use appropriate personal protective equipment when working on vehicles or machinery and match socket sizes precisely to fasteners to minimise slippage.
