Socket set AWTools AW39173 — 173-piece, 9.5 kg

AWTools AW39173 — 173-piece socket set weighing 9.5 kg. This comprehensive kit contains a broad range of sockets, ratchets, extensions, bit adapters, screwdriver bits and allen keys, all organized in a durable plastic case. Components are manufactured from hardened and tempered CrV and CrMo steel and include 1/4", 3/8" and 1/2" drive tools with 72-tooth ratchets to enable a minimal 5° swing for work in confined spaces.

Advantages

The set offers a wide coverage of metric socket sizes and torx/bit options suitable for many fastening and maintenance tasks. Hardened CrV and CrMo construction ensures wear resistance and long service life. Three drive sizes and multiple extension lengths provide flexibility for both shallow and deep fasteners, while the compact plastic case keeps the components organized and portable.

Suitable for

• Automotive repair and maintenance
• Plumbing installations and repairs
• Mechanical assembly and disassembly
• Electrical equipment servicing (non-live work)

How to use

Select the appropriate drive and socket size for the fastener, attach the socket to the ratchet or extension, and engage the ratchet direction switch as required. Use extensions or cardan joints to reach recessed or angled fasteners. For screwdriver bits, fit the required bit into the bit adapter or the 1/4" driver handle. Apply steady torque and avoid excessive impact forces beyond the tool’s intended mechanical limits.

Usage recommendations

Keep sockets and bits clean and lightly lubricated on moving parts (ratchet mechanism and extensions). Match socket size precisely to fastener to reduce rounding. Store the set in its plastic case to prevent loss and to protect components from corrosion. For high-torque or impact applications, use tools and sockets rated for such use; this set is intended for manual fastening and repair tasks.
