Brownells Magna-Tip Thin-Bit #340-2

Description

Product Overview

Brownells Magna-Tip Thin-Bit #340-2 is a precision screwdriver bit made for extra-narrow screw slots commonly found on firearms and gunsmithing assemblies. At .340 SD with .025 BT, it’s designed to fill the slot for controlled engagement, helping reduce the risk of damaging small screw heads.

Key Features

• Designed for extremely narrow screw slots encountered during gunsmithing
• Thin-bit geometry (SD .340 / BT .025) for tight-fit screw engagement
• Magna-Tip magnetic retention helps keep small screws aligned during work
• Hardened bit construction for durability when used carefully on properly seated screws
• Works best when the blade fills the slot edge-to-edge and side-to-side

Use with care on firmly seated hardware for best results, and keep the bit properly matched to the screw slot for smooth, confident turns.
