Minerallac 38503D #2 x 3" Phillips Power Bit, 1/4" Hex Shank

The Minerallac 38503D is a #2 x 3" Phillips drive power bit built with a 1/4" hex shank for fast, secure use in cordless drills, power drivers, and impact drivers. Sized for a full 3" length, this bit is designed to drive Phillips-head fasteners commonly found on wallplates, wiring devices, panelboard covers, receptacle mounting screws, and general electrical hardware. The 1/4" hex shank drops directly into standard quick-change chucks and bit holders, making the 38503D a practical, ready-to-grab addition to any electrician's tool pouch or service truck. Its #2 Phillips tip is sized to match the most common fastener head found on electrical devices and enclosures, helping crews keep moving from box to box without hunting for the right bit.

Minerallac 38503D – Frequently Asked Questions

1) Will the Minerallac 38503D power bit fit my impact driver's quick-change chuck?
Yes. The 38503D has a 1/4 inch hex shank, which is the standard quick-change connection on cordless drivers, impact drivers, magnetic bit sleeves, and multi-bit screwdriver handles. It drops straight in with no adapter. It will also chuck into a standard three-jaw drill chuck if that is what you have on hand.
2) Is a #2 Phillips the right tip size for receptacle and wallplate screws?
It is. The #2 Phillips is the tip that matches the fastener head found on most wallplates, wiring devices, receptacle mounting screws, panelboard covers, and general electrical hardware. The Minerallac 38503D is a #2 x 3 inch Phillips drive bit, so one bit covers the bulk of device work on a trim-out.
3) I need to drive square recess screws, not Phillips - what should I use instead of the 38503D?
The Minerallac 38503D only drives Phillips-head fasteners; its tip is a #2 Phillips profile. For square recess (Robertson) fasteners, the Milwaukee SHOCKWAVE Impact Duty 2 inch square recess power bit is the correct tip style. Square recess screws are common on panel and device hardware from some manufacturers, so many electricians carry both tip styles rather than substituting one for the other - a Phillips tip in a square recess head will cam out immediately.
4) What is the closest equivalent to the Minerallac 38503D Phillips power bit if I need more reach?
The Minerallac 38503D is a #2 Phillips drive bit measuring 3 inches long with a 1/4 inch hex shank. If you need to reach deeper into an enclosure or a recessed device box, the Milwaukee 48-32-4802 SHOCKWAVE Impact Duty bit is also a #2 Phillips but runs 6 inches in length. Both drive the same #2 Phillips fastener head, so the tip engagement is identical and the difference is purely the shank length between the chuck and the screw.
5) Is the Minerallac 38503D an impact-rated bit like the Milwaukee SHOCKWAVE bits?
The Milwaukee 48-32-4802 and the Milwaukee 2 inch square recess bit are both part of Milwaukee's SHOCKWAVE Impact Duty series, which is the designation Milwaukee uses for its impact-driver line. The Minerallac 38503D is a steel power bit built for use with cordless drills, power drivers, and impact drivers, with a 1/4 inch hex shank that drops into standard quick-change chucks and bit holders. If your purchasing spec calls out a named impact-duty series, the SHOCKWAVE part numbers carry that series designation.
6) For wallplate and receptacle screws, do I want the 3 inch Minerallac 38503D or a 6 inch bit?
For surface work like wallplates, cover plates, and receptacle mounting screws, the Minerallac 38503D at 3 inches gives enough reach while keeping the bit short enough to stay stable in the chuck. The Milwaukee 48-32-4802, a #2 Phillips at 6 inches, suits fasteners set far back behind a panel face or inside a deep enclosure. Both are #2 Phillips tips, so choose on how far the screw sits from the driver nose.
7) What is the Minerallac 38503D made of and where is it made?
Steel construction, made in Taiwan. The 38503D is a single-piece steel power bit with the #2 Phillips tip and 1/4 inch hex shank formed on the same shaft, so there is no joint to twist apart in a driver.
