Product Number: S3818
Variations
A poorly fitted or low-quality socket can round fasteners and slow down professional work. The Sealey S3818 is an 18mm standard-depth socket for 3/8" square drive, built for daily professional use as part of Sealey's comprehensive Premier Hand Tools range. Cold-forged from Chrome Vanadium steel and hardened and tempered for added strength, it delivers durability under repeated use. The WallDrive® configuration grips the flat faces of fasteners rather than the corners, reducing wear and the risk of rounding. The chrome-plated half-chrome, half-satin finish is complemented by a knurled ring for a secure hold even when hands are oily. Backed by Sealey's lifetime guarantee.
