The TIMCO M6 x 30mm Carriage Bolt and Hex Nut set is designed for professional carpenters, woodworkers, and DIY enthusiasts needing a reliable, secure fastening solution for timber-to-timber or ironmongery-to-timber connections. Its standout feature is the square anti-spin shoulder, which prevents the bolt from rotating during tightening, ensuring a flush and secure fit. However, users should note that the grade 4.8 carbon steel construction is intended for general interior or moderate use and may require additional protective coatings if exposed to harsh, highly corrosive outdoor environments.

These M6 nuts typically require a 10mm wrench or socket.
They feature a zinc finish which offers basic protection, but they are best used in sheltered or dry environments.
Yes, they are specifically designed for attaching ironmongery to timber, provided the load does not exceed the capacity of Grade 4.8 steel.
This refers to the tensile strength and yield strength of the steel, indicating it is suitable for general-purpose rather than heavy structural engineering.
No, the pack includes bolts and hex nuts only; you may need to purchase M6 washers separately if required by your application.
Ensure the square shoulder is properly seated into the timber by tapping the head firmly with a hammer.
Check the bolt threads for debris or wood shavings and clear them; use a light machine oil if resistance persists.
To ensure a professional finish, always use a drill bit consistent with the M6 diameter. Because the bolt relies on the wood grain to hold the square shoulder, avoid re-drilling the same hole multiple times, as this can strip the wood and cause the bolt to spin. While the zinc finish is durable, avoid using these bolts in direct contact with treated timbers that contain highly acidic preservatives, as this can accelerate corrosion. Store your remaining bolts in a dry, low-humidity environment to prevent white rust formation on the zinc surface.
