About this item
  • Made of high-quality 410 stainless steel with superior corrosion resistance, perfectly suited for the damp, rainy climate. These self drilling screws resist rust, oxidation and water damage when used outdoors on fascia, cladding, roofing and garden metal structures, delivering long-lasting secure fixing without premature degradation.
  • This all-in-one kit includes 6 commonly used M4.2 countersunk self drill screw sizes to meet all your fixing demands: M4.2×13(100pcs), M4.2×16(100pcs), M4.2×19(50pcs), M4.2×25(40pcs), M4.2×32(15pcs×2). Comes with 1 free matching Phillips screwdriver bit for instant use. Ideal for light metal, thin steel plate, timber & composite cladding projects.
  • The integrated sharp drill point cuts through thin steel, metal sheet and wood effortlessly, eliminating the tedious pre-drilling step. Cross recess countersunk head sits flush flat into materials for a neat, seamless finish; sharp threads grip tightly to prevent loosening, perfect for DIY enthusiasts, tradesmen, roofers and handymen across.
  • Supplied with a sturdy transparent plastic storage case with separated labelled grids, each size is individually stored to avoid mixing up screws. Compact lightweight design is easy to carry to job sites, garages, workshops or home DIY tasks; the secure snap-lid prevents screws spilling during transport.
  • Versatile self drilling screws widely used for metal roofing, wall cladding, shed frames, guttering, window trim, fence brackets, furniture assembly, HVAC ducting and general metal-to-wood fixing. Suitable for professional builders, electricians, plumbers as well as home DIY repairs, renovations and garden construction projects.

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.
