Self tapping insert with 3 blind holes


Self-tapping insert with 3 blind holes – industrial grade threaded insert for secure metal and composite assembly
The self-tapping insert with 3 blind holes is a heavy-duty industrial screw-in threaded insert designed to cut its own internal thread in a pre-drilled hole, eliminating the need for pre-tapping and ensuring long-lasting screw retention and mechanical strength across demanding B2B fastening applications.
Description
Product description and long-tail SEO focus for B2B applications
This self tapping threaded insert with 3 blind holes and hardened steel construction combines three precision cutting bores with a specially designed non-metric outer thread to automatically form a durable internal thread in materials such as aluminium alloys, reinforced plastics, HPL (high-pressure laminate), duroplastics and composites. Its design makes it ideal for industrial assembly lines, mechanical manufacturing, maintenance operations, metal-to-composite fastening solutions and structural thread repair.
Technical specifications, material codes & tolerance details
• Internal thread sizes available: M4, M5, M6, M8, M10, M12, M14 and M16 providing versatility for metric industrial hardware and high-strength fasteners.
• Material variants: Hardened steel with zinc plating and stainless steel 303 for enhanced corrosion resistance and wear performance in industrial environments.
• Blind self-tapping cutting holes: Three closed cutting bores allow metal chips to exit cleanly, preventing chip entrapment and ensuring a clean, precision internal thread for subsequent screw insertion or repeated assembly cycles.
• Outer thread profile: Specially engineered with a smaller thread angle for self-tapping capability and high pull-out strength in softer receiving materials.
Installation guidance & B2B manufacturing efficiency
• Installation tools: Compatible with manual installation tool 610 or mechanical installation tool 620, both securing the insert’s internal thread during mounting and ensuring consistent torque and alignment.
• Pre-hole preparation: Drill an accurately sized pilot hole with a slight chamfer; no thread tapping necessary.
• Ease of use: “Drill, screw and done” approach significantly reduces assembly time, lowers labour cost, and improves output quality for high-volume production environments.
Industrial applications & advantages for B2B OEMs
This self-tapping insert is widely used in:
• Industrial machinery & assembly production – reliable internal threads for frequent assembly/disassembly and vibration-resistant fastening.
• Light metals and composite panel fabrication – secure screw joints in HPL, aluminium or high-strength plastic materials.
• Maintenance, repair & operations (MRO) – effective thread repair insert for worn or stripped holes, restoring part functionality without full replacement.
• Automotive, furniture manufacturing and metal-to-plastic fastening systems where consistent thread quality and durable internal threads are essential.
