Self-tapping vs machine screws: which one when?
2026-08-14
Compiled by JIALI Industrial (164.hk) — a Hong Kong fastener supplier specialising in screws, bolts, nuts and selection know-how.
Self-tapping
Has drilling/self-cutting threads; drives directly into sheet metal, wood, drywall without pre-tapping.
Machine screws
Need a nut or tapped hole; load is more even, ideal for removable and load-bearing joints.
Quick pick
Thin sheet metal, wood, drywall → self-tapping; structural or disassemble joints → machine screws.
