M6 x 40mm Star Grip Thumbscrews with Plastic Head, 12 Pack

Sturdy and Reliable Fixing These M6 x 40 mm knurled thumb screws are manufactured from high-quality carbon steel with a zinc-plated, corrosion-resistant surface. The clearly defined threads provide a firm grip that resists slipping and loosening, making them a dependable choice for securing components in industrial equipment, tool fixtures and furniture assembly. The robust construction ensures lasting fastening strength and structural stability, even in environments where components are subject to regular use. Durable Plastic Head Each star grip screw features a one-piece injection-moulded plastic head with a high-gloss polished finish. This material offers excellent resistance to abrasion, corrosion and oil exposure, while remaining non-conductive and non-magnetic. As a result, these screws help prevent electrical signal interference, making them well suited to equipment with high insulation requirements. Comfortable and Efficient Handling The ergonomic six-lobe plastic handle is shaped to fit the hand comfortably, allowing fatigue-free operation during prolonged tightening or loosening. As a clamping screw, it can be adjusted manually with speed and precision, then locked securely in place. This makes the screws particularly useful in confined working spaces or for tasks that require frequent adjustment, helping to improve overall efficiency. Versatile Applications These M6 star grip knobs are suitable for a wide range of uses, including assembling furniture such as adjustable parts of tables, chairs and cabinets, setting up tents by securing or adjusting components, and carrying out routine operation and maintenance on machinery. They are also practical for adjusting displays, electrical devices and medical instruments. Designed for repeated dismantling and quick adjustments, these screws help save time across various projects.
