Customer Reviews for Wing Screws 5.5 x 40mm Pack of 100
"I used these beyond their specification in that I was fixing down 18mm plywood sheets to a checker pattern mezzanine floor. Worked very well, even though I should have used the longer ones to fix, all I had to do was let the ribbed head bore it's way into the plywood. Just wish they were a bit cheaper as they only come with 100 to a box."
"These work very well and can save a lot of time. But beware, the thread length is not given in the description, only the overall length. If the short threaded length might cause a problem then consider choosing the "EASIDRIVE" screws."
