• Ergonomic quad-lobe handle design with 360 deg texture for additional grip
• Designed to meet demanding heavy duty needs of industrial maintenance
• Impact and chemical resistant handles are four sided with broad but shallow flutes
• Resistant to most harsh chemicals (including hydraulic fluids used in the aerospace industry)
• Four sided handle design helps prevent roll away from the work surface
• High alloy steel shanks are heat treated their entire length to help provide strength against twisting action and to help prevent bending and twisting when placed under torque
• Fully grounded and chemically polished, then chrome plated for corrosion resistance
• Precision machined for precise fastener fit
• Finished in black oxide to help prevent cam out and slipping
• Tips are un-plated with a black oxide finish to help prevent chrome peeling, an important foreign object debris (FOD) concern
