Makita B-43365 Hollow Socket 3/4 x 12 in - Faster Overhead Fastening

Our review of the Makita B-43365 Hollow Socket finds it to be a focused tool for anyone who regularly pistons nuts onto long bolts or threaded rod in elevated or tight locations. The single biggest reason to buy is its extended hollow design combined with a press-fit 1/4in hex shank, which lets you run an impact driver or driver-drill while the fastener passes through the socket, saving significant time compared with hand threading. This review looks at who benefits most, how it performs on typical jobs, and whether it is worth adding to a contractor or serious DIY kit.

Key Features

• Hollow shaft: Lets long bolts and threaded rod pass through so you can drive nuts without pre-threading, speeding overhead fastening tasks.
• 12 point socket: Provides an easier fit over both 6-point and 12-point fasteners for quick engagement on varied hardware.
• 12 in length: Gives better access to nuts in hard-to-reach ceiling, ductwork, or strut rack locations compared with standard sockets.
• Axial press-fit 1/4in hex shank: Delivers greater durability and torsional strength so it withstands impact driver forces better than single-piece hollow bits.
• Chamfered inner well: Prevents the driver shaft from biting threads, reducing damage and making fastening and unfastening smoother.

Who It's For

The B-43365 is ideal for electrical contractors, HVAC installers, and anyone installing strut racks or running threaded rod through ceilings where access is limited; the extended hollow design and impact-driver compatibility dramatically reduce time spent hand-threading nuts. It also suits maintenance techs who need a durable socket that fits both 6- and 12-point fasteners and holds up to repeated impact use.

Casual users with only occasional short-bolt work or those who never use an impact driver may find the long hollow design unnecessary and could opt for a standard socket set instead. This is a specialty bit intended to streamline specific overhead and all-thread applications.

Pros & Cons

Pros

• Built to save time on overhead fastening by allowing threaded rod to pass through the socket.
• Durable press-fit 1/4in hex shank stands up to impact driver torque.
• 12-point head and chamfered inner well reduce slippage and protect threads during driving.
• Long 12 in reach improves access in ceilings, ductwork, and strut installations.

Cons

• Specialty length and hollow design are unnecessary for users who rarely work with long bolts or all-thread.
• Because it is a single-purpose socket, you may still need other sockets for general-purpose work.

Our Verdict

The Makita B-43365 Hollow Socket is a smart addition for professionals and serious DIYers who frequently work with all-thread or long bolts in ceilings and tight spots; its extended hollow length, durable press-fit hex shank, and 12-point design save time and reduce frustration. It represents good value for those specific tasks, though casual users who rarely need long hollow reach can stick with standard sockets instead.
