A: They are made of 304 stainless steel, which offers strong resistance to rust and corrosion. While they can withstand occasional rain and humidity, for continuous saltwater exposure you may eventually see some surface discoloration. For most garden, deck, and outdoor furniture projects, they will hold up beautifully.
A: Yes, these are designed to be paired with a standard metric nut or threaded insert of the same size. For example, an M6 wing screw needs an M6 nut. Many customers use them with T-nuts, threaded inserts in wood, or directly into tapped aluminum profiles.
A: In this kit, the longest available option is 40mm for M8 and M10. If you need longer wing bolts, please send us a message – we occasionally can source custom lengths up to 55mm upon request.
A: Absolutely. The wide wing head distributes pressure well, and when combined with a threaded insert in plastic or resin, these thumb screws create a strong, tool-free joint without cracking the surrounding material.
A: 304 stainless steel is generally considered non-magnetic or only slightly magnetic after cold working. They should not stick strongly to a magnet, which is a good indication of their corrosion-resistant quality.
