- Cup Head Coach Carriage Bolts are used to attach wood to wood or steel with a matching nut to clamp the materials together. The coach bolt has a low profile domed head and a square section under the head which resists turning when the nut is tightened or removed. The square section pulls into the wood as the nut on the other end is tightened, thus eliminating the need for a second spanner. Used to support structure, in timber framing, outdoor furniture, fencing and retaining walls, a common example is the seat and back slats of your garden bench and table furniture
- Material / Coating: Marine Grade Stainless Steel A4-70 G316 is the ultimate corrosion resistance fastener. Designed to be used in all conditions. The best fastener for marine, coastal, chemical and food environments. Stainless steels are largely non-magnetic but it is common for stainless steel fasteners to show a small degree of magnetism which is a result of work-hardening during the manufacturing process. Some of our stock have a smooth finish with no head markings, if required Test Certificates or Certificate of Conformity can be requested
- Can Stainless corrode?: Stainless steel is corrosion-resistant but not corrosion-proof and corrosion can occur if the material is installed or handled incorrectly. The use of tools and drills made from conventional steel during the installation of stainless steel fasteners may also lead to problems. Even the hardest of tools can produce debris that leaves minute steel particles on the stainless steel fastener surfaces or in pre-drilled holes. It is these particles that often rust when exposed to moisture or oxygen and can result in a stained or tarnished finish to the stainless steel material
- Grade v Class Difference: Metric fastenings are referred to as classes and imperial as grade. Both generally have head markings to determine grade and class. The markings on a stainless fastener indicate the grade of material and strength, e.g. material G304 grade will have one of the following markings: A2-70, G304, A2, 304 and G316 grade stainless will have one of the following: A4-70, G316, A4, 316. Some sizes do not have head markings, we have no control of this as it depends on the stock available at the time
- Thread Pitch (Metric): Pitch means the distance between the peaks of two threads along a screw, bolt, or fastener expressed in millimetres (mm). Used when referring to Metric parts. For example, a thread pitch of 1.50mm means that the distance between one thread and the next is 1.50mm
- Fastener Length: Is generally measured from the point where the surface of the material will be when the fastener is installed to the end of the fastener. Thus, fasteners with heads that sit above the surface are measured from under the head to the end of the fastener, while fasteners that sit flush with the surface are measured from the top of the head to the end of the fastener
