Set Screws
Why the Point Style Genuinely Isn’t a Cosmetic Choice
A set screw is fully threaded and headless, seating entirely within a tapped hole in a hub or collar, with only its point protruding to contact the shaft. Unlike a conventional bolt, which clamps two surfaces together by bearing its head against one of them, a set screw’s entire holding torque depends on the point’s ability to grip the shaft directly, with no head bearing surface involved at all.
Here is why this matters. Because different point styles engage the shaft differently, a cup point genuinely creates a sharp circular biting edge that digs into the shaft surface for genuinely high holding power, but this genuinely mars and damages the shaft, making precise readjustment or reuse of that exact shaft surface harder afterward. A flat point, by contrast, genuinely provides no digging action at all and relies purely on friction from clamping force, genuinely preserving the shaft surface undamaged, but delivering genuinely lower holding power for the same tightening torque. This is why point style selection is a genuine trade-off between maximum holding torque and shaft surface preservation, not a cosmetic choice.
A genuine, honest limitation is worth stating plainly. Because this trade-off is genuine and application-specific, buyers must confirm whether their shaft surface genuinely needs to remain undamaged and precisely re-adjustable, where a flat point is genuinely the right choice, or whether maximum resistance to slippage is the primary genuine concern and marking the shaft is genuinely acceptable, where a cup point is genuinely the right choice. Simply ordering set screws without specifying point style, or assuming the standard cup point is always correct, can genuinely result in either insufficient holding torque or unwanted permanent shaft damage, depending on which concern actually governs the application.
Akbar Fasteners Pvt. Ltd. exports to over 50 countries, and our set screw range is manufactured and verified for point geometry and mechanical property compliance under our ISO 9001:2015 quality system.
A Note on Confirming Shaft Preservation vs Maximum Grip
Please confirm whether your shaft surface genuinely needs to remain undamaged and re-adjustable, or maximum holding torque is the primary concern, when requesting a quote — this determines the correct point style.

Cup Point vs Flat Point Set Screws — Quick Reference
Confirming whether your shaft genuinely needs to stay undamaged and precisely re-adjustable, or maximum resistance to slippage is the primary concern. This table is the quick reference we use with buyers before quoting.
| Aspect | Cup Point | Flat Point |
|---|---|---|
| Holding Torque for Same Tightening | Genuinely higher | Genuinely lower |
| Shaft Surface Damage | Genuinely marks and mars the shaft | Genuinely preserves the shaft undamaged |
| Best Fit | Genuinely permanent, high-slip-risk mounting | Genuinely precision, re-adjustable shafts |
