Proto JK14112R Stubby Slotted Keystone Screwdriver 1/4 in

• Designed to meet demanding heavy duty needs of industrial maintenance and assembly applications.

• Screwdrivers meet ASME B107.15 standards.

• Made in USA. HANDLE

• Impact resistant, extruded acetate handles are four-sided with broad but shallow flutes.

• Resistant to most harsh chemicals (including hydraulic fluids used in the aerospace industry).

• Handles are comfortable and easy to hold.

• Four sided handle design helps prevent ”roll away” from the work surface.

• Large handle size provides a strong grip for extra driving power. SHANK

• 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.

• Large round shanks include hex bolster for use with a wrench when added torque leverage is required.

• Bars are securely anchored into transparent handles for long life. TIP

• Made of high-alloy steel (same as Shank).

• 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.

• Proto Tools have been manufactured in the USA for over 110 years, made to standards suitable for stringent aerospace requirements and heavy mining applications.
