Description
Overview:
The Thin Wall Spark Plug Socket Set 3/8"D 3pc is a compact, high-strength set for removing and installing spark plugs in tight, recessed plug wells on modern petrol engines. Made from durable chrome vanadium steel, each socket is engineered with a super-slim wall and a 12-point (Bi‐Hex) profile to help reach plugs where clearance is limited. A rubber insert grips and cushions the plug's ceramic insulator for safer handling and reduced risk of damage. The set covers common plug sizes: 14 mm (O.D. 18 mm), 16 mm (O.D. 20.4 mm) and 18 mm (O.D. 23 mm), each with a 63 mm length suited to compact engine bays. Compatible with 3/8" (9.5 mm) drive ratchets, extensions and torque wrenches used across automotive, motorcycle, garden and small plant maintenance.
Key Features:
- Thin-wall design for access to narrow plug tubes and confined engine bays
- 3/8" (9.5 mm) square drive for broad tool compatibility (ratchets, extensions, torque wrenches)
- Sizes included: 14 mm (O.D. 18 mm), 16 mm (O.D. 20.4 mm), 18 mm (O.D. 23 mm)
- Short 63 mm body helps manoeuvre past coil packs and surrounding components
- 12-point (Bi‐Hex) profile for positive engagement and smooth drive in tight spaces
- Rubber inserts to hold plugs securely and protect fragile ceramic insulators
- Chrome vanadium steel construction for strength, durability and long service life
- Clean, corrosion-resistant finish for easier wipe-down and maintenance
- Ideal for aluminium cylinder heads where cautious, precise plug handling is essential
- Suitable for professional workshops and DIY servicing where limited clearance is common
Typical Applications:
Routine spark plug changes and inspections on modern cars, vans and motorcycles with recessed plugs; servicing small engines on garden machinery and compact plant equipment; working around tight plug wells, coil-on-plug systems and alloy heads; use with 3/8" (9.5 mm) drive hand tools and torque wrenches to install plugs to the correct specification without damaging the plug or the head.
