براغي رأس أسطوانية M20-2.5 × 75mm | محرك سداسي | ملولبة جزئياً | ستانلس ستيل 18/8 (25 / العبوة)

The hex socket drive seated perfectly on my Allen wrench with zero wobble, and the 18/8 stainless finish looks clean against the steel frame I bolted together. Threads ran smooth the whole 75mm length, no binding even in a tight pre-drilled hole. These are exactly what I needed for the precision ass

Put these in a jig I was building and the 18/8 stainless feels solid, no corrosion worries. The hex socket drive seated perfectly with my Allen wrench on the first try.

The partially threaded design on these M20-2.5 screws made installation into my tooling jig much easier; I didn’t have to fight with full threading. The 18/8 stainless feels solid, and the hex socket drive holds the Allen key securely without slipping. Exactly what I needed for a machinery rebuild.
