Spring pins are one of the most common types of mechanical fastener, and are used across all kinds of industries, including: Proper Hole Alignment: Ensure the holes in both components are aligned accurately to allow smooth insertion of the roll pin. Dowel Pins: Dowel pins are rigid pins used for accurate alignment of two components. They ensure precise positioning and prevent misalignment. Use the Right Tools: Utilize a roll pin punch or installation tool to prevent damage to the pin and components.

Gentle Tapping: Tap the roll pin gradually into the hole using light, controlled strikes to avoid deformation or misalignment. Spring pins are general purpose components used across a wide range of fastening applications. They are hollow, tube-like fasteners, usually made from carbon steel, alloy steel, or stainless steel. We specialise in the larger diameters of Spring Tension Pins 13mm, 14mm, 16mm, 18mm, 20mm, 21mm, 22mm, 24mm, 25mm, 28mm, 30mm, 32mm, 35mm, 38mm, 40mm, 45mm, 50mm, 62mm which conform to one of the following standards BS7060 DIN8752 DIN1481 and ISO8752 The pins are suitable for applications where vibration is involved, by inserting one pin inside another double shear strength can be produced although one pin will be suitable for most applications producing approx 10% more strength than a solid mild steel pin. Roll pins are commonly made from materials such as carbon steel, stainless steel, and other alloys. Carbon steel roll pins offer good strength and cost-effectiveness, while stainless steel roll pins provide corrosion resistance, making them suitable for outdoor or corrosive environments. The choice of material depends on the application's requirements and environmental conditions.

Flexible Connection: Roll pins provide a degree of flexibility, accommodating slight misalignments or movement. As it is installed, the spring pin is compressed - applying constant pressure on each side of the hole wall. This allows users to provide a secure fix to various parts of a machine, with the spring pin acting as a self-retaining fastener between parts. For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. Unwanted Food or Drink Products - Once supply conditions are broken, there are a number of factors outside of our control that can affect the quality of a product. Therefore perishable goods such as food and drink cannot be returned. Spring tension pins are used in a variety of applications and industry to include Electrical , Automotive , Agricultural , White products , Turning and Milling machines. For further technical specifications call our sales team who can advise on tolerance and shear strength etc.

The reusability of roll pins depends on their condition after removal. If a roll pin is intact, undamaged, and within its specified tolerances, it can potentially be reused. However, careful inspection is necessary to ensure that the pin's structural integrity has not been compromised during removal. Roll pins that show signs of deformation, wear, or damage should be replaced with new ones to maintain the reliability of the connection.Reputable fastener suppliers offer a wide range of high-quality roll pins, catering to various needs: If you are using the roll as an edging then dig a trench where you want the roll to run, the depth of trench will depend on the height on the log roll you have and how much of it you want showing above the ground. Ideally aim to have 50-75mm (2-3ins) below ground level. If your log roll is more than 10 ins (250mm) high do consider using extra support for the retained soil, above 18ins (450mm) extra support is definitely recommended. Roll pins Some times know as Spring Tension Pins or Selloc Pins ,Roll pins are manufactured from a high grade carbon spring steel or where corrosion resistant is required grade A2( 303 ) stainless steel and Heat treated for maximum strength (CARBON STEEL ONLY). Vibration Resistance: The design of roll pins allows them to absorb and withstand vibrations without loosening.

Cost-Effectiveness: Roll pins are generally economical fastening solutions suitable for various applications. Spring pins (often referred to as 'roll pins') are a commonly used fastener type than allows users to securely fix various parts and materials together. Cromwell's range of spring pins are designed to meet all leading standards, for ultimate strength, reliability, and peace of mind. Easy Replacement: If necessary, roll pins can be removed and replaced without significant damage to the components.

Make sure the bottom of your trench is level by running a marked stake along the length. The roll is very flexible, so curves are quite OK. If you're looking for personalised recommendations about the right type of spring pin to use for your applications, ask our experts for specialised advice.
