## Description

Cup Head Carriage Bolts or Hex Bolts for Timber.   6mm x 30mm fully threaded Pack of 25   Mild Steel coach bolts have a corrosion resistant zinc coating and are ideal for 99.9% of applications.   Domed Head A domed head bolt with a square anti spin shoulder mainly used for clamping timber or attaching ironmongery to timber. B Point B point for use in pre-drilled shallow holes. Cup square carriage bolts DIN603 and hexagon nut DIN934 are mostly used in wood. They are fully threaded upto 150mm, it has a domed top and a square under the head which grips into the part being fixed, preventing the bolt from turning when the nut is tightened.  Timber is an organic product that’s constantly moving, low tensile fasteners that will accommodate this movement plus if the bolted joint isn’t allowed to flex it could snap a stiffer fastener or the local timber around the bolt.   Mild steel bolts are very strong and it is virtually guaranteed that most timber will break, way before the bolt, so using high tensile bolts for timber is a wasted expense.   Cup Square Hex Bolt and Nut has a rounded cup shape with a square lug underneath with a hex nut on the other end.   It is this lug and large cup head that makes this bolt so useful for timber because as you tighten the lug bites into the wood and locks it to stop it turning while the large surface area cup head stops it pulling through.
