Product Description

Medical Hexagonal Cone Inner Hole Drive Head 316L Stainless Steel

Product Description

Product Application:
This component is a precision-engineered internal drive interface designed for transmitting torque in medical and surgical devices. Its specific geometry is critical for the secure assembly, adjustment, and disassembly of sensitive medical instruments.

Orthopedic & Trauma Surgery: Used in drivers for bone screws, locking bolts, and implant set screws (commonly as a "hexalobe" or similar anti-slip interface).
Dental Implants & Prosthetics: Serves as the drive socket for abutment screws, prosthetic retaining screws, and implant placement tools.
Minimally Invasive Surgical (MIS) Instruments: Internal drive for laparoscopic tool tips, reusable handpiece attachments, and adjustable mechanism locks.
Medical Device Assembly: Provides a reliable, cam-out resistant drive for critical fasteners inside medical electronics, pumps, and diagnostic equipment.
 
Product Description:
The Medical Hexagonal Tapered Internal Drive Head is a high-precision internal socket featuring a hexagonal profile with tapered sidewalls. This design offers superior engagement with a matching male driver bit, minimizing slippage ("cam-out"), distributing stress evenly, and allowing for higher torque transmission in compact spaces. Often referred to by proprietary names (e.g., Torx Plus, Hexalobe), this geometry is favored in medical applications for its reliability and ability to withstand repeated sterilization cycles without wear. Typically manufactured from high-grade stainless steel (e.g., 17-4PH, 316L) or titanium, the component is machined to exacting tolerances to ensure perfect bit fit, preventing fastener damage and ensuring procedural safety. It can be a standalone insert or machined directly into a screw head, implant, or tool component.
