Uxcell Taper Pins Review: Reliable GB117 fastening for small repairs

Fasteners for repair and alignment that lock parts securely using hardened carbon steel pins. Uxcell Taper Pins suit DIYers and workshop users who need dependable, repeatable fastening. Are the 40mm length and GB117 standard the right fit for your project?

⚡ At a Glance

• Holding Strength: 45# carbon steel combined with a hardening heat treatment for robust mechanical connection
• Best for: DIYers, metalworkers and workshop technicians needing standard GB117 taper pins for alignment
• Not ideal for: Applications that require non-metallic, decorative or corrosion-resistant fasteners

Hardened 45# carbon steel taper pins, 40mm long with a 4mm small end diameter made to GB117. Heat treatment increases surface hardness for improved wear resistance during assembly.

Secure fastening, with 45# carbon steel

45# carbon steel is a medium-carbon material that accepts hardening, giving higher strength and resistance to shear when heat treated. Hardening heat treatment changes the metal microstructure to improve surface hardness without altering the basic taper geometry.

Strong, wear-resistant pins keep small assemblies locked under load, reducing loosening in repeated use. Suitable for mechanical joints where a solid metal fastener is required.

Accurate alignment, with GB117 taper and 4mm small end diameter

The GB117 standard defines taper geometry for pins so mating holes and bores can be produced to matched dimensions. A defined small end diameter of 4mm helps achieve repeatable positioning when driven into tapered holes.

Consistent taper shape helps locate parts precisely during assembly, making alignment quicker and reducing the need for shims or adjustments. Works well where repeatable positioning matters, such as jigs and fixtures.

Durable finish, with hardening heat treatment

Hardening heat treatment increases surface hardness and wear resistance by controlled heating and quenching. The finish reduces surface wear that occurs from insertion and removal cycles, extending usable life.

Pins maintain shape and fit through multiple assemblies, so replacements are needed less often. That reliability suits workshop repairs and recurring maintenance tasks.
