How to Identify High Tensile Bolts for Your Projects
Quick & Easy: How to Identify High Tensile Bolts When your project demands extra strength – whether it's for a vehicle upgrade or heavy machinery – high tensile bolts are a must. At AIMS Industrial, we’re here to help you understand what to look for in a fun and easy way. Understanding Bolt Grades Bolt grades indicate the strength and durability of the bolt. In Australia, you will commonly encounter these grades: Grade Description 8.8 Medium carbon steel, quenched and tempered 10.9 Alloy steel, quenched and tempered for extra strength 12.9 Alloy steel with the highest tensile strength How to Identify High Tensile Bolts Look for the grade markings stamped on the bolt head – these numbers tell you the bolt’s strength: 8.8: Marked with "8.8" 10.9: Marked with "10.9" 12.9: Marked with "12.9" Choose the Right Bolt for Your Application Not every project requires the same level of strength. Here are some of our top picks available at AIMS Industrial: Metric Hex Bolt - Grade 8.8 High Tensile Zinc Finish – Ideal for many structural applications. Bumax 10.9 Stainless Steel High Tensile Hex Bolt – Perfect for projects needing extra corrosion resistance. M20 x 24 x 80 Socket Head Shoulder Screw Plain High Tensile G12.9 – The top choice when maximum strength is essential. Safety, Time and Money Selecting the right high tensile bolt is crucial for the safety and longevity of your projects. Always check the bolt head for grade markings and choose the one that best fits your application. Explore our full range of high-quality fasteners on our Bolts Collection for more options.

Best Practices on V-Belt Installation & Maintenance
Get it right the first time—optimize your belt life, system performance, and uptime. Installing and maintaining a V-belt isn’t just about fitting it on the pulleys. It’s about maximizing belt lifespan, reducing downtime, and ensuring safety. At AIMS Industrial, we support your process with easy-to-understand guides that make belt maintenance easier and more accurate than ever. How Do I Install a V-Belt Properly? Power off all equipment and ensure its locked out. Fit the belt over the pulley grooves—do not force or stretch it. Adjust pulley positions to allow proper belt fit. Tension the belt according to spec (see next section). PRO TIP: Use a Belt Tension Tester to get accurate results every time.Choose from our: Single barrel tester (15kg) – ideal for individual belts Double barrel tester (30kg) – perfect for joined or multiple belts Both options are designed to measure belt tension accurately during installation or routine maintenance, helping extend belt life and minimise downtime. How Do I Tension a V-Belt? Use a tension gauge or follow the manufacturer’s deflection recommendations. Too loose = slippage. Too tight = bearing wear. How Often Should V-Belts Be Inspected? Check belts as part of your routine maintenance schedule—ideally: Monthly for high-use or industrial applications Quarterly for moderate-use machines Look for cracks, fraying, misalignment, or stretching. What Causes V-Belt Slippage? Incorrect tension Worn or dirty pulleys Oil or grease contamination Excessive wear or age How Do I Prevent V-Belt Misalignment? Use a straightedge, laser alignment tool, or pulley alignment app. Misaligned belts cause heat buildup, uneven wear, and energy loss. What Are the Signs of V-Belt Wear or Failure? Replace the belt if you see: Cracks or splits Glazing or shine Squealing noises Frayed edges Belt slipping or jumping Don’t wait until failure—proactive replacement saves cost and downtime. How Do I Replace a V-Belt? Power off and lockout the system. Loosen the tensioner or move pulleys to release the belt. Remove the worn belt and inspect pulleys for damage. Install the new belt, ensuring no twists or forceful stretching. Tension and align using proper tools or manufacturer specs. Can I Use Multiple V-Belts on the Same Drive? Yes—and no need to match if you're using high-tolerance belts like Gates.They stretch slightly in use, compensating for minor length differences. But with Aramid/Kevlar belts, matching is essential—they don’t stretch at all. Tip: Always replace all belts in a set together. Mixing old and new leads to uneven wear and reduced lifespan. Do V-Belts Require Lubrication? No. Never lubricate a V-belt. Keep belts and pulleys: Clean Dry Free from oil, grease, and debris Contaminants reduce grip, increase slippage, and deteriorate belt material. Final Thoughts Proper installation and maintenance of your V-belts can extend equipment life, reduce downtime, and save money. With smart tools, AI-driven support, and a commitment to an exceptional user experience, AIMS Industrial is here to make every belt install easier, safer, and more reliable.
