Dowel Pin with Internal Thread (DIN7979D)

Dowel Pin with Internal Thread (DIN7979D), also known as Threaded Dowel Pin, Pull Out Dowel Pin, Extractable Dowel Pin, Internal Thread Dowel Pin or Threaded Locating Pin, is a precision cylindrical locating pin with an internal thread at one end. It is used for accurate positioning, alignment and location of machine parts, while the internal thread allows easier extraction during maintenance or disassembly.

Unlike a standard dowel pin, the internal thread provides a practical removal feature. A screw, threaded puller or suitable extraction tool can be used to pull the pin out from a blind hole or tight-fitting assembly. This makes it very useful for moulds, dies, jigs, fixtures, machine plates and mechanical components that may need periodic servicing or replacement.

Dowel Pin with Internal Thread (DIN7979D) is commonly used in precision machinery, tooling, mould bases, die sets, fixture plates, machine frames, automation equipment, equipment housings and industrial repair applications where accurate alignment and future removal are both important.

Why Choose Our Dowel Pin with Internal Thread (DIN7979D)

Choosing the correct Dowel Pin with Internal Thread (DIN7979D) is important for alignment accuracy, hole fitment, extraction, wear resistance and long-term assembly reliability. The pin should match the diameter, length, internal thread size, tolerance, material, hole size, extraction method and application requirement.

Harden Steel Dowel Pin with Internal Thread is a practical option for machinery, moulds, dies, jigs, fixtures, tooling plates, machine frames, equipment covers and industrial mechanical assemblies. Harden steel construction helps improve durability in selected positioning and alignment applications.

The internal thread is the key advantage of this pin. It allows the pin to be removed more easily compared with a plain dowel pin, especially when installed in a blind hole. This is useful for maintenance teams, mould makers, fixture builders and machine repair users who need accurate location but also require future disassembly.

Dowel pins with internal thread are often used together with screws and clamping fasteners. The dowel pin controls accurate alignment, while screws provide clamping force. This combination helps improve repeatability and reduces the risk of assembly misalignment.

Users should not order only by outside diameter. Internal thread size, pin length, tolerance and hole fit are also important. For best performance, the hole should be prepared correctly, usually by drilling and reaming according to the required fit. For high-load, high-precision, safety-related or critical machinery applications, pin tolerance, hole tolerance, interference fit, internal thread strength, material hardness and assembly design should be checked by a qualified person or project specification.
