Locating Pin Large Head, Selectable Tapered Angle, Selectable Tolerance, Threaded

The positioning pin is used for the spatial positioning in the directions of X and Y axes, mainly using the workpiece hole as the positioning benchmark or used in conjunction with bushings, in which the large head tapered specified tolerance selection type offers flexible selection and can meet most customer design requirements.

Precision grade tolerance cannot be selected for hard chrome plated products.
The D section of the austenitic stainless steel type has an identification groove.
Austenitic stainless steel may be ground or have no center hole.

P·L·B() dimensions are suitable for polygonal types.
When L=0, there is an incomplete thread section with no undercut groove.
Since the front-end diameter must be greater than ⌀0.73, P, E, and A must satisfy the following condition formula. P —2EtanA ≥ 0.73 Reference: tan15° ≈0.267, tan30° ≈0.577, tan45° =1, tan60° ≈1.732
Hard chrome plated products cannot select tolerance symbols with * (Precision Grade A, B)
E-BKFN series products are temporarily unable to support polygonal manufacturing. We appreciate your understanding!
