FAQS on m6 countersunk bolt 80mm
Q: What is an M6 countersunk bolt 80mm used for?
A: An M6 countersunk bolt 80mm is designed for flush mounting in materials like metal or wood. Its tapered head sits level with the surface, making it ideal for applications requiring a smooth finish, such as machinery or cabinetry.
Q: Can I use an M6 x 80mm carriage bolt for outdoor projects?
A: Yes, M6 x 80mm carriage bolts are often galvanized or stainless steel, providing rust resistance. Their rounded head and square neck prevent spinning, making them suitable for outdoor structures like gates or fencing.
Q: Are M6 x 80mm furniture bolts compatible with all wood types?
A: M6 x 80mm furniture bolts work with most woods, including hardwoods and plywood. Their decorative domed head and integrated washer distribute pressure evenly, minimizing damage to softer materials like particleboard.
Q: How to install an M6 countersunk bolt 80mm correctly?
A: Drill a pilot hole matching the bolt’s shank diameter. Use a countersink bit to create a tapered recess for the head. Tighten with a hex key until the head sits flush with the surface.
Q: What’s the difference between carriage bolts and furniture bolts in M6 x 80mm?
A: Carriage bolts have a square neck to lock into materials, while furniture bolts feature a decorative head and built-in washer. Carriage bolts suit structural work, whereas furniture bolts prioritize aesthetics in assemblies like shelves or tables.
