About this item
- Floor board screws are specially designed for installing wood floors into truck trailers
- Six-Lobe Recess Flat Heads (Floorboard)
- Self Tapping Thread Cutting Screws - Measure length from the top of the head to the tip
- Black Phosphate and Oil Finish. The oil serves as a rust inhibitor and a lubricant. However, this does not sanction use in wet or exterior situations
- The head design of Floorboard Screws provide a flush surface in countersunk holes. For this reason, they are perfect in floorboard fastening applications.

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.
