Lisle 12990 17mm/17.5mm Dual-Size Flip Socket

The Lisle 12990 is a dual-size flip socket designed for the removal of standard and damaged lug nuts commonly found on passenger vehicles. This double-ended impact socket features 17mm on one end and 17.5mm on the other, making it ideal for removing swollen or damaged chrome-capped lug nuts where the chrome layer has separated from the steel core.

Key Features:

• Dual hex sizes (17mm/17.5mm) in one reversible socket
• 6-point design for secure grip and reduced rounding
• Impact-rated construction from chrome molybdenum steel
• Black oxide finish for corrosion resistance
• 1/2" drive compatible
• Part of Lisle's flip socket system (sold separately in set 12950)

This specialized socket eliminates the frustration of dealing with bloated or corroded lug nuts by offering two sizes in one tool. Simply flip the socket to access the size you need, whether working with factory lug nuts or those that have expanded due to chrome cap deterioration.
