Industrial 8249004 Bit Socket 3/8 Hex 90mm Length 4mm

Sonic 8249004 is a 3/8-inch drive hex bit socket, 90 mm long, designed for 4 mm hex bits. It’s crafted from chrome-vanadium steel and chrome-plated for durability in demanding workshop environments. The 90 mm overall length provides extended reach to fasteners in tight or recessed areas, making it well suited for automotive maintenance and equipment repair where standard-length sockets can’t access the fastener head. The 4 mm hex bore accepts standard 4 mm hex bits, allowing quick bit changes without leaving the tool. This part is cataloged as 8249004 by Sonic Equipment GmbH and appears in European catalogs and retailer listings under descriptions like “Bitdop hex long 3/8'', 90mmL, 4mm.” Verified listings exist from Fabory, Winparts, Mekonomen, and ToolTeam, reflecting consistent sizing across markets. Some listings note that it includes a wall hanger for storage.
