M10 Cup Square Hex Coach Bolts Stainless Steel [Grade 304 A2]

• These coach bolts are stainless steel, and ideal for timber to timber joining.
• The threaded length on these is 60 percent of the total length, although some may have longer depending on manufacturer.
• Also known as 'cup square hex bolts', the square underneath the cup stops rotation of the bolt when tightening.
• Conforms to DIN603 and DIN934 standards.
• A range of nuts to suit are available separately.

APPLICATION
Used mainly for fastening timber to timber and is extensively used for timber joist construction in house building and numerous decking applications.

A carriage bolt, also known as coach bolt or as cup square hex bolts, has a domed head, and the shank is topped by a short square section under the head. The square section grips into the part being fixed (typically wood), preventing the bolt from turning when the nut is tightened. A rib neck carriage bolt has several longitudinal ribs instead of the square section, to grip into a metal part being fixed.

Stainless steel does not readily corrode, rust or stain with water as ordinary steel does. However, it is not fully stain-proof in low-oxygen, high salinity, or poor air-circulation environments. There are different grades and surface finishes of stainless steel to suit the environment the alloy must endure. Stainless steel is used where both the properties or steel and corrosion resistance are required.
