As a leading Slotted Nuts Manufacturer in India, New Star Industries supplies high-strength nuts built for one of the most safety-critical locking methods in mechanical engineering — the split pin. Unlike a standard nut that relies purely on friction and thread tension to stay tight, a slotted nut is mechanically locked in place, making it the preferred choice wherever a joint absolutely cannot be allowed to loosen.
A slotted nut is tightened onto a bolt with a matching cross-drilled hole, and a split pin is then passed through the slot and the hole — physically preventing the nut from ever backing off, regardless of vibration or shock loading. We manufacture our slotted nuts in grades 8 and 10, conforming to IS 2232 or produced strictly as per customer drawing.
✓ Positive Mechanical Locking: The slotted design allows a split pin to pass through the nut and bolt, physically preventing rotation rather than relying on friction alone.
✓ High Strength for Safety-Critical Joints: Manufactured in grades 8 and 10, our slotted nuts are built for applications where joint failure isn't an acceptable risk.
✓ Metric and Inch Thread Options: Available in sizes from M10 to M64 (1/2″ to 2″) with both metric and inch threads, covering a wide range of automotive, railway, and machinery drawings.
✓ IS 2232 Compliance: Manufactured to IS 2232 where standard sizing applies, or strictly as per customer drawing where a specific slot position or size is required.
✓ Vibration and Shock Resistant: Once pinned in place, the joint stays locked through continuous vibration and shock loading, making it suitable for the most demanding operating conditions.
Slotted nuts from New Star Industries are widely used in automotive, railway, and heavy machinery applications where a joint must be mechanically locked rather than relying on friction alone — commonly specified on axle assemblies, suspension components, and other safety-critical connections subject to continuous vibration.
Beyond IS 2232 standard sizes, New Star Industries manufactures slotted nuts strictly as per customer drawing, matching size, thread type, and slot configuration to your exact requirement. Share your drawing with our team, and we'll manufacture to your precise specification.
