For reasons of hygiene and safety, personal grooming products, cosmetics or items of intimate clothing cannot be returned. As a general rule of thumb, it is recommended that spring pins are fitted in a hole with a diameter the same or 0.1mm larger than the diameter of the pin. The expanded diameter should be 0.2-0.3mm larger than the diameter of the pin. Reputable fastener suppliers offer a wide range of high-quality roll pins, catering to various needs: 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. Gentle Tapping: Tap the roll pin gradually into the hole using light, controlled strikes to avoid deformation or misalignment.

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. Use the Right Tools: Utilize a roll pin punch or installation tool to prevent damage to the pin and components. 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

Proper Hole Alignment: Ensure the holes in both components are aligned accurately to allow smooth insertion of the roll pin. Spring pins are one of the most common types of mechanical fastener, and are used across all kinds of industries, including: 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. 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. Now using a flat board on top of the log roll, tap along the length to get the tops all the same height and horizontal. Then drive in the stake at the other end and attach the log roll to this.

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. Dowel Pins: Dowel pins are rigid pins used for accurate alignment of two components. They ensure precise positioning and prevent misalignment. 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.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. 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. Vibration Resistance: The design of roll pins allows them to absorb and withstand vibrations without loosening.
