Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive

Product Brief :

This Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive is from Qimao Metal Manufacturer. The head has an external hex and an internal Torx socket. You can drive it with a standard wrench, a socket, or a Torx key. That flexibility matters in real work.

The external hex gives you the torque capability of a standard hex bolt. The internal Torx gives you a second option when a socket won’t fit or when you want a more secure engagement at high torque. Torx drives distribute force across six lobes instead of six points, which reduces the chance of rounding the head.

We make these from carbon steel or stainless steel. Threads are rolled for strength. Sizes from M6 to M12, with custom lengths available. It is a simple idea, but it solves a real problem.

Product Details

Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive external hex head plus internal Torx socket. Drive with a wrench, socket, or Torx key. Carbon steel or stainless steel. Metric threads, M6 to M12. Class 6g tolerance. Hex drive sizes from 10mm to 18mm. Torx socket from T30 to T50. Rolled threads for strength. Plain, zinc plated, or black oxide finish. The Torx socket engages six lobes, not six points, so it resists rounding better than a standard hex socket. Fits machinery and automotive assembly. Custom lengths and materials available on request. Bulk or custom packaging. When a socket won’t clear the head, the Torx key gives you a second option. That is the whole point of dual drive.

Key Features:

• Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive of Two drive options, one bolt. External hex for standard sockets. Internal Torx for Torx keys or bits. Use whichever fits the job.

• Torx resists rounding. The six-lobe Torx profile engages more surface area than a hex socket. Less chance of stripping when you lean on it.

• Fits tight spaces. When a socket won’t clear the head, a Torx key can get in from the side. This is the reason dual drive exists.

• Material options. Carbon steel for general assembly. Stainless for corrosion exposure.

• Custom sizes. Send a drawing or sample. We match thread, length, and finish.

Use Cases:

• Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive for Machinery assembly. Wherever a hex bolt works but you want a backup drive option.

• Automotive under-hood. Space is tight. A Torx key sometimes fits where a socket won’t.

• Equipment maintenance. If a hex head is partially rounded, the Torx socket gives you a second chance before you reach for the extractor.

• Fixtures and jigs. Repeated assembly and disassembly. Dual drive gives the operator options.

• High-vibration environments. Torx engagement holds better under vibration than hex socket alone.

Installation Notes

1. Pick your drive. The Dual Drive Hex Torx Bolt – Hex Head with Internal Torx Socket for Machinery & Automotive for maximum torque with a socket. Internal Torx for tight access or when you want more engagement.

2. Check thread size and pitch. Metric coarse and fine both available. Match your application.

3. Start by hand. Two or three turns before you put a tool on it. Cross-threading is the enemy.

4. Torque properly. Use the correct torque value for your bolt grade and application. Over-torque will strip threads or snap the bolt. Under-torque and it loosens.

5. Lubricate when needed. A light oil on threads helps consistent torque and prevents galling, especially with stainless.

6. Inspect after first run. Vibration settles joints. Recheck torque after the first operating cycle.
