Caution
Product Description
- Locating Pins - High Hardness Stainless Steel, straight (Press Fit) from MISUMI.
- A straight positioning pin made of high hardness stainless steel.
- Insertion Guide Tip Type can be selected into 3 types, Tapered, Tapered R or Spherical.
- Tapped type locating pin provided tapped thread for disassembled.
- For tapped type, unless described otherwise on the drawing, the spec, design is the same as for Press fit type.
- The tightening torque (ref. value) is tightening torque strength class 10.9. Not applicable when using locking materials or lock washers.
● Tapered ● Sphere 
[ ! ] For SUS316L, except when the L dimension is short (2 mm or less), an identification groove will be added at any position on the D part.

| [ M ] Material | [ H ] Hardness | Tip Shape | Type | Features |
| Press Fit | ||||
| High Hardness Stainless Steel* | 35HRC or more | Tapered | ALPSTA | An austenitic stainless steel that offers both hardness (35 HRC and above) and corrosion resistance, providing a cost-effective and well-balanced option. |
| Sphere | ALPSQA | |||
| High Strength Stainless Steel | 55HRC or more | Tapered | ZLPSTA | A martensitic stainless steel with hardness equivalent to SUS440C (55 HRC and above) and superior corrosion resistance compared to SUS440C. |
| Sphere | ZLPSQA | |||
| SUS316L | - | Tapered | XLPSTA | This is an upgraded material compared to SUS304. This is a low-carbon, more corrosion-resistant, non-magnetic austenitic stainless steel. |
| Sphere | XLPSQA |

■Shear Testing Results
*Locating pins (same size as JPBB6-8) are set on the fixture
and a load applied with a universal tester to measure the shearing load.
| Material | Shear Load | Hardness |
| High Strength Stainless Steel | 33kN | 55HRC or more |
| High Hardness Stainless Steel | 26kN | 35HRC or more |
| SUS304 | 20kN | 10 to 20HRC |
| SKS3 Equivalent | 33kN | 60 to 63HRC |
| SUS440C | 31kN | 50 to 55HRC |
and a load applied with a universal tester to measure the shearing load.
