A2 Stainless Cup Square Hexagon Bolts
A2 Stainless Steel Cup Square Hexagon Bolts
Our A2 Stainless Steel Cup Square Hex Bolts are also sometimes known as coach bolts or carriage bolts. They are ideal for use in timber connections as the square section under the mushroom head pulls into the timber enabling the bolt to be tightened without the head spinning. The mushroom or domed head gives a neat appearance.
These Cup Square hex bolts are produced to DIN603/555 out of A2 Stainless Steel so are ideal for external applications. They are usually either fully threaded or over 100mm long have approximately 100mm of thread. We also supply some sizes in Galvanised steel or A4 Stainless Steel.
The bolts are NOT normally supplied with hexagon nuts as standard so please order these separately. They are often used in conjunction with repair washers, square plate washers and timber connectors which can be purchased separately.
For marine and salt water applications or highly corrosive environments we recommend the use of our A4 (316) Stainless Steel products instead of A2 (304) Stainless grade.
