The TIMco Carriage Bolt and Hex Nut set is designed for DIYers and professional builders who need a reliable solution for fastening timber or attaching ironmongery. Featuring a classic domed head and square anti-spin shoulder, these grade 4.8 carbon steel bolts provide excellent clamping strength for structural wood projects; however, they are finished in zinc and should be monitored for oxidation if used in highly corrosive or coastal environments.

This model is an M6 bolt with a length of 60mm.
Yes, each bolt is supplied with a matching hex nut.
Yes, they feature a zinc finish suitable for standard outdoor use, though they are not rated for marine or highly corrosive environments.
The square shoulder under the head is designed to bite into the wood when the bolt is properly seated, preventing rotation.
They are manufactured from grade 4.8 carbon steel.
Ensure the square shoulder is fully seated in the timber; tap the head of the bolt with a hammer to engage the anti-spin shoulder.
You may have used an oversized drill bit; consider using a washer to distribute the pressure or re-check the required hole diameter for M6 bolts.
For optimal results, ensure the timber is free of debris before insertion. If the bolt is difficult to push through, verify that the hole is clear of sawdust. To prevent the Zinc finish from degrading, avoid using abrasive cleaning pads or strong chemical solvents. Periodically check that the nuts remain tight, especially in timber projects that may shrink or expand due to moisture changes over seasonal cycles.
