- Jaw & Swage Rigging Screws also known as bottlescrews, are specifically suited for adjusting the tension of stainless steel wire rope. With a removeable pin, and pivot, these fasteners easily adjust on a secured post or frame, and can easily be attached to a saddle or lag screw eye, providing a professional and timeless look
- Benefits / Features: Bottlescrews can be swaged (crimped) to wire rope. Used to adjust tension and reduce slack in a rope, cable or similar tensioning assembly. Rigging Screws are primarily sized according to the diameter of wire with which they work and they are used in concert with other fittings – normally with a similar swaging style – that work with the same diameter of wire rope. ASME B30.26 - Rigging Hardware defines a turnbuckle as “an adjustable device consisting of three primary components: a body, a right-hand threaded end fitting, and a left-hand threaded end fitting.”
- Breaking Load:
Maximum Tensile Force = 10.79kN or 1100Kg.
The tensile strength of a material is the maximum amount of tensile stress (pull) that it can take before failure measured in Kilonewtons (kN) or kilograms-force (Kg). BL or Breaking Load is a similar measurement.
PLEASE NOTE: Safe working load is recommended at approximately 20% of maximum tensile force. - Testing and Breaking Load: It is the Purchasers responsibility to determine whether the testing procedure and if provided, the breaking load is suitable for purpose
- Material / Coating: Marine Grade Stainless Steel A4-70 G316 is the ultimate corrosion resistance fastener. Designed to be used in all conditions. It is the best material for marine, coastal, chemical and food environments. Stainless steels are largely non-magnetic but it is not uncommon for stainless steel fasteners to show a small degree of magnetism. This is partly due to the work-hardening of the product during the manufacturing process. Marine Grade Stainless Steel A4-70 G316 can be easily identified by the following markings: A4, A4-70, A4-80,316 or G316
- 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
- Seizing, Binding or Galling?: All Threads will seize under high tension. It is a well-known and accepted problem especially when using Stainless Steel or other alloys such as aluminium, etc. As pressure builds between the contacting and sliding surfaces protective oxides are broken, possibly wiped off, and interface metal high points shear or lock together. This cumulative clogging-shearing-locking action causes increasing adhesion. In the extreme, galling leads to seizing (the actual freezing together of the threads). If tightening is continued the fastener can be twisted off or its threads ripped out. The frequency of threads seizing can be reduced by using anti-seize compounds, but not eliminated. There are also other ways to minimize the occurrence of thread seizing, Keep the thread clean and away from dirt and grit, etc. Tighten the thread slowly. Work them back and forth occasionally to feel if it is tight when loosening. If the thread starts to feel like it is heating up it is because the metal threads are rubbing against each other under high tension. This can be an early sign that it may seize due to overloading. It may be that you need to go up a size to reduce the overloading. Seizing is not a product fault but is the nature of Stainless Steel material
