THE MOST PREMIUM 8 mm IN EXISTENCE. The lightest, tightest fitting socket using the best materials and coatings. 100% Corrosion proof. Non-marring to most fasteners. Available as standard or blemished. Blemished sockets have faded size markings, slight surface imperfections - the strength and performance of the socket is not affected. Features of the TRO Titanium 8 mm Socket: LIGHTWEIGHT YET STRONG. Titanium provides similar strength to steel at 56% of the weight. Our optimized designs take this even further. ULTRA-lightweight at 3.8 g (0.13 oz) - Half the mass of a normal socket and still 42% lighter than a lightweight steel 8 mm socket. Beautifully machined from Titanium (Ti-6Al-4V). High Quality surface finish inside and out. ENGINEERED FOR THE ULTIMATE FIT. Experience the absolute tightest fitment on fasteners, reducing stress and preventing rounding. Exceptionally tight clearances. Sockets and drives machined to exceptionally tight tolerances for a near-perfect grip. A near perfect fit on hex fasteners fasteners. TRO Titanium Plug Socket image shown for example: Zero Play = more surface engagement, less stress on both thre tool and fastener. They're also less prone to marring delicate fasteners. Extremely strong retention design on the 1/4" square drive. 100% non-magnetic and corrosion-proof. Nearly non-marring to fasteners due to high contact area and slightly less hardness than steel (~42 vs 52 HRC). CUSTOMIZABLE HIGH-PERFORMANCE COATINGS. Choose a coating that matches your style and performance needs. Several high performance PVD Coatings Offered: Standard Charcoal DLC is our recommendation. It combines the best combination of wear resistance, low friction, price and coating adhesion/coverage/surface roughness. COATING SURFACE HARDNESS (VICKERS) THICKNESS (μm) FRICTION COEF.
