Color:Black
Specification Code:MS3170-ST
Specification Description: Steel‚Resetting type
[Body] Steel, black finish
[Pin Head] Polished nickel plated AISI 303 stainless steel. It is recommended to fit holes conforming to H8 tolerances.
[Locking Screw] (for BK, CK and GK types).
High impact strength polyamide-based (PA) high-tech polymer, black, matte finish (type B and BK). Resistant to solvents, oil, grease and other chemical solvents.
[Knurled Locking Grip] High impact strength special high-tech polymer, black, matte finish (type C and CK). Resistant to solvents, oil, grease and other chemical solvents.
[Standard Type] Type B: with kneader, no locking nut. Type BK: with knead and locking sphenoid, according to SO 8675
The MS3170-ST index pin has the following advantages:
1. Each pin head ∅ has two retractions (1); 2. Type B and type C have smaller specifications;
3. Part of the retract device (type C) is covered; 4. Limit the length of the thread through the cut at the thread end
Index plunger pin provides controlled movement and firm hold in mechanical setups, automation lines, and production tools. Reliable, cost-effective, and easy to use—our index plunger pin delivers smooth indexing and consistent performance.
