Eye Bolt Collar Kit is a bolt with a collar and a closed eye at one end. Designed to screw through panels beams or engineered shade sail structures used in balustrading and industrial markets. This fitting is not to be used for lifting Length: The length measurement for a collar eye bolt length is from under the collar to end of thread (t) 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 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. All material is advisory only and its use by anyone is entirely voluntary. Reliance on it for any purpose by anyone is at the sole risk of that person and Bolt and Nut Australia is not responsible for any loss claim or damages arising therefrom.
