The ends of the wrench are chamfered to allow them to slip easily into the fastener, eliminating wrench wear and damage to the fastener head. Instead of layers of plating, each wrench's steel surface is treated directly with a black oxide finish. This finish will not damage your work or degrade the precision fit in fasteners over time because it will not flake or chip.

• Precisely sized, chamfered, straight ends offer a snug fit and insert smoothly into the fastener head, reducing wear
• Sizes from T10 to T50, star-shaped wrench. Comes with 9 keys.
• Chrome vanadium finish protects against corrosion without added plating that could chip off under high-stress contact
• Specially treated steel ensures long-term use.
• Longarm/short arm design offers extended reach on one end and extra leverage on the other
