Stahlwille 12030003 Increaser Piece 4 — BOLTON SKU 52806.
About the 12030003 Stahlwille Increaser Piece
The 12030003 increaser piece is a Stahlwille square-drive adaptor carrying a 3/8 in drive square on one side and a 1/2 in drive square on the other, listed under order number 12030003. It allows a 3/8 in ratchet, extension or torque wrench to drive sockets, deep sockets and universal joints from the 1/2 in range. As with every increaser, the adaptor changes the coupling and nothing else: the 3/8 in tool behind it still determines the practical torque ceiling, and the presence of a larger socket should not be read as permission to load the joint harder. Supplied as a single adaptor, it is a common gap-filler in kits that are built around 3/8 in drive but occasionally meet fasteners whose hex size is only stocked in the larger range.

Typical applications
Larger hex sizes, impact-pattern hand sockets and specialist profiles are frequently held only in 1/2 in drive, so this increaser is what keeps a 3/8 in torque wrench usable on those fasteners when the specified setting is well within its range. It also has an access role: the slimmer 3/8 in ratchet head clears obstructions that a 1/2 in head fouls, while the socket on the joint stays full size. Mobile and containerised tool kits carry one to avoid duplicating an entire socket range.
