💡 When should I opt for self drilling taps over conventional machine bolts? Switching to self taping hardware trims your timeline while boosting joint stability on thin gauge metals. Here is how they stack up for your next build day. - Punching pilot holes wastes shop time and strips edges on soft alloys - Combined drilling and threading actions maintain consistent clamp load across joints - Handier workflow means fewer tool swaps and cleaner panels on the fly - Corrosion ready finishes keep outdoor rigs solid through rainy seasons
