3-7/8" 12-Point Combination Wrench

The Gray Tools 3324 combination wrench fits 3-7/8" hex fasteners with a 12-point broached opening for a tight, secure grip. Its satin chrome finish resists corrosion in garage and shop environments. The tool meets ANSI dimensional standards. It is suited for mechanics and maintenance crews working on large equipment.

Installation and common issues

Slide the box end or open end onto the fastener and apply steady torque; the precision broaching reduces rounding risk. The 12-point geometry allows engagement at finer angles in confined spaces. Overtorquing beyond the fastener rating can still damage threads or the wrench. California Proposition 65 warnings note chemicals linked to cancer and reproductive harm.

Behaviour under sustained load

The chrome plating holds up to repeated heavy use without flaking, maintaining corrosion resistance over time. Broached corners retain their shape during high-torque applications on large bolts. Heat from prolonged work does not degrade the finish or fit. The wrench is not designed for impact drivers or hydraulic torque multipliers.

Questions about this item

How can I verify the 12-point broaching is engaging correctly on a fastener?

The precision broached 12-point opening should seat fully and flush on the 3-7/8" hex without rounding the corners when torque is applied.

Does the wrench come with any storage tray or organiser, or must I purchase one separately?

The product is the single combination wrench only; any tool storage tray or organiser is sold separately.

Is the 3324 model the only size in this finish, or are other hex sizes offered in satin chrome?

The 3324 is the 3-7/8" size; other hex sizes in the same satin chrome finish carry different model numbers.
