Dowel Pins

we are manufacturers of all sizes of circlips ( internal, external, `e` clips) , shims , dowel pins. All products are manufactured from high carbon spring steel material.

we manufacture all type of dowell pins (hollow type) in all sizes varying from 1 m.m. To 8 m.m. Nominal dia and length from 4mm to 140m.m.

all dowell pins are manufactured from high carbon spring steel material with ends chamfered. 

specifications of dowel pin (hollow) are as follows;-

notes;-
1. Insertion of a combination pin is more difficult than a single pin.
2. Both ends must be chamfered ( grinded) to save labour and to facilitate installation and removal.
3. Lenth and dia. May be in plus but not in minus.
4. Industrial safety glasses should be worn when installing pins/parts.
5. Re-useable.
6. Self- locking and self - aligning
7. All pin dimensional sizes secified are prior to the addition of any plating or surface treatment.
