SATA ST09003SJ 5PC 3/8” Drive Metric Spark Plug Socket Set

Item is new but may or may not have factory sealed packaging.

The SATA ST09003SJ is a professional-grade 5-piece 3/8" drive metric spark plug socket set expertly configured to simplify deep-seated engine plug service. Weighing just 1.76 lbs inside its molded storage tray, this specialized system relies on an offset flex-head ratchet that moves smoothly around obstructions to offer supreme knuckle clearance. Built with thin-walled chrome vanadium steel sockets featuring internal rubber protection inserts, a 15-degree wobble extension, and a secure locking extension to stop loose sockets from pulling off in deep engine wells.

Specifications

• Offset Flex-Head Ratchet: Features a pivoting ratchet head paired with an offset body design to easily clear adjacent engine components and achieve the perfect angle on stubborn spark plugs.
• Dual Wobble & Locking Extensions: Includes a flexible wobble extension for bypassing angular obstructions, paired with a solid locking extension that guarantees your socket won't pull loose and get stuck inside a deep engine cylinder cylinder head.
• Protective Rubber Socket Inserts: The 16mm and 21mm single-hex 6-point sockets feature internal rubber cushions that firmly grip the spark plug for easy removal while shielding the porcelain shell against cracked surfaces.
• Industrial Thin-Wall Sockets: Engineered from heat-treated alloy steel to precise industrial specifications, maintaining an ultra-thin wall profile to smoothly glide into narrow spark plug wells where thick sockets won't fit.
