برغي، قلاووظ M2.2x9.5 رأس دائري فيليبس

The Phillips head seated perfectly flush in my machinist's jig, exactly as the SC4-189 spec promised. Threads bit clean into the aluminum without any galling. A solid little fastener for precision bench work.

Exactly the right size for the SC4-189 part, and the Phillips head seated perfectly without stripping on first use. These little tapping screws are a lifesaver when you need precision in a machinist setup.

Used these to repair a drawer slide on an old bench, and the round head seated perfectly flush. The M2.2 thread grabbed the metal firmly without stripping. Exactly what the SC4 parts diagram called for.
