Hex Drive Magnetic Nut Setter - 3/8 in. x 1-7/8 in.

This magnetic nut setter (Item # BIT-45064) is constructed of chrome vanadium steel and features a lobular design that drives fasteners on flat sides instead of corners to reduce stripping. It includes an extra strength magnet secured with a splined brass bushing, a 1/4" power hex shank, and is built to endure high torque from impact drivers.

Key features:

• Chrome vanadium steel construction
• Lobular design to reduce nut corner stripping
• Extra strength magnet held by a splined brass bushing
• 1/4" power hex shank for impact driver compatibility

Q: What are the specifications of a 3⁄8-in × 1-7⁄8-in magnetic nut setter?
A: This size indicates the nut-setter socket is sized for 3⁄8-in-hex (or hex-head) fasteners, with a bit length of approximately 1-7⁄8 inches and a standard ¼-in hex shank to fit most drills and impact drivers.

Q: What advantage does the magnetic feature provide for this nut setter?
A: The built-in permanent magnet holds nuts or screws securely on the bit, reducing fastener drops and wobble during driving, which improves speed and accuracy—especially useful in overhead or tight-space work.

Q: In what applications is a 3⁄8-in magnetic nut setter most useful?
A: It’s ideal for driving 3⁄8-inch hex-head bolts, machine screws, self-tapping fasteners in sheet-metal, HVAC, framing, rack-assembly or any application where fasteners must be driven quickly with a power driver and fastener retention matters.

Q: What usage and maintenance practices should I follow to keep the bit performing well?
A: Use the correct driver (¼-in hex shank), avoid side-loading or prying with the bit, keep the magnetic tip clean of metal shavings or debris, inspect for rounding of the socket or wear, and replace the bit when it no longer holds fasteners securely or begins to strip.
