Frequently Asked Questions
Q: What drill types are compatible with this self-tapping socket adapter?
A: This adapter features a standard 1/4-inch (6.35mm) hex shank, making it compatible with virtually all hand-held electric drills and cordless drill drivers that accept 1/4" hex shank bits. Simply insert it into your drill chuck like any other hex bit.
Q: What is the difference between the M6, M8, and M10 sizes?
A: The size refers to the thread diameter and pitch of the fastener the adapter drives. M6×1.0 suits smaller screws and bolts (6mm diameter), M8×1.25 is a mid-range size (8mm), and M10×1.5 handles larger fasteners (10mm). Choose the size that matches the self-tapping screws, hanger bolts, or screw insert nuts used in your project.

A: Yes. The double-tooth design includes an internal thread for driving double-ended screws (hanger bolts) and an external thread for installing screw insert nuts, giving you two functions from one compact tool.
Q: Is this adapter made of durable material?
A: Absolutely. This socket adapter is crafted from chrome vanadium steel (Cr-Mo alloy), which offers excellent hardness and wear resistance for long-lasting performance across repeated use on wood, metal, and composite materials.
