Spoon screw

Ensures high-level holding power with coarse thread! Effective on hardwood and wood knots, etc.

The "Spoon Screw" is a wood screw designed for wooden substrates, featuring a spoon-shaped drill bit at the tip made of thin steel plate (approximately 1.0 mm) that allows for penetration. As it is screwed in, it cuts through the wood fibers and creates a pilot hole, thereby preventing wood splitting. It is particularly effective on hard woods and knots in wood, ensuring a high level of holding power with its coarse thread design. 【Features】 ■ Cuts through wood fibers and creates a pilot hole while being screwed in, preventing wood splitting. ■ Effective on hard woods and knots in wood. ■ Ensures high holding power with coarse thread design. ■ Suitable for fastening to a wide range of wooden substrates, including hard wood building materials and resins. *For more details, please refer to the PDF document or feel free to contact us.
