In today’s very competitive environment where technology is continually advancing, industries and companies are taking advantage of the recent innovations in procedures and products to improve productivity and profitability. Without exemption is the humble yet very efficient chemical threadlocker. This product has seen increasing application in the past years, particularly on service bays and assembly lines. Thanks to the developments made in chemistry which made threadlockers even more versatile and meet even wider variety fastening requirements.
The key benefit of using a threadlocker than a mechanical fastener is that it provides better torque retention. Mechanical fasteners can lose their elasticity over time, or due to vibration and heat. This is where chemical threadlockers become valuable and addresses such fastening issue. However, one major drawback with threadlocker is during disassembly where special tools and procedures will be required, especially in the case of high-strength threadlockers. In addition, it’s also crucial to choose the best threadlocker for specific tasks. With that, here are some important details about each type of chemical threadlockers to help you decide.
- Low-strength: this type is ideal for relay lock screws, fuel injection and carburetor fasteners, body panel mounting fasteners, and other fasteners with up to 6 mm.
- Medium-strength: threadlockers under this category is suitable for fasteners from 6 mm to 20 mm. They provide good vibration resistance and work well for the likes of starter and alternator bolts, U-joint bolts and nuts, intake manifold and valve cover bolts, and fasteners for engine-mounted accessories.
- High-strength: this threadlocker is perfect for nearly or permanent assemblies where fasteners are larger than 20 mm, such as in the construction of equipment fasteners, engine block bolts, axle bolts and nuts, and truck bed mounting bolts.
By determining the type and size of fasteners you are going to use with chemical threadlockers as well as other essential factors, definitely you will find the best product you need.
