The most Premium Spark Plug Socket on the market.
The lightest, tightest fitting design using the best materials and coatings - a classic tool taken to the next level.
Features of the TRO 3/8" Drive Titanium Spark Plug Socket:
- Beautifully machined from Titanium Ti-6AL-4V (Grade 5). High quality surface finish inside and out.
-
Exceptionally tight clearances. Both Hexes and the square drive offer much better fitment than standard tools. A near perfect fit.
- With minimal play between the plug and tool, more of the socket is engaged, reducing stress on the tool and the plug hex.
- Extremely strong retention on the 3/8" square drive. Extensions will not accidentally release, leaving the socket behind.
-
Available in Charcoal Black DLC (Diamond Like Carbon), Gold TiN (Titanium Nitride) or **Iridescent DLC coatings. The Iridescent coating is one of the hardest and slickest coatings in existence @ >6600 Vickers (65 GPa) hardness.
Uncoated sockets are available, but not recommended - bare Titanium is less wear resistant than Steel.
**IRIDESCENT DLC colors vary greatly - the sockets may be predominantly green, pink or yellow at random.
