About this item
  • This set comes with 32 pieces M4 x 20mm Phillips cross flat head self tapping wood screws crafted from premium 304 stainless steel. The 304 stainless steel material delivers reliable rust resistance, oxidation resistance and wear resistance, effectively resisting moisture in indoor environments and maintaining stable long-lasting clamping force for furniture and cabinet mounting projects.
  • Each M4 flat head wood screw features deeply engraved, tidy and evenly spaced threads. Pressure distributes uniformly during tightening to eliminate thread slippage risk, firmly locking plywood, softwood and chipboard without loosening under minor vibration, perfect for daily shelf assembly and wood DIY repairs.
  • Every self tapping fastener adopts standard Phillips cross recess flat head design, which fits the supplied short & long magnetic screwdriver bits tightly. The precise cross slot avoids screwdriver bit slipping during manual or electric tightening, cutting down installation time and lowering labour effort for all carpentry tasks.
  • The fastener assortment includes total 32PCS M4 x 20mm 304 stainless steel flat head self tapping screws plus 2 dedicated magnetic cross screwdriver bits. All accessories are sorted separately in a clear compartment plastic storage box, convenient for classification, transport and quick retrieval during home renovation, craft making and furniture fitting.
  • Versatile M4 Phillips cross flat head self tapping screws suit various light wood fastening applications. Ideal for small furniture assembly, cabinet trim fixing, wooden shelf mounting, handmade craft production, window frame decoration and general household minor wood repair replacement fasteners.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
