Knurled-knob piercing pins need positioning inputs that locate the pin axis and grip zone on the controlled layout instead of relying on a familiar knurl photo.
Identify the fixture or cover revision that controls piercing-pin position, the knurl grip zone needed for hand adjustment, and the approval owner. The threaded-stud product route helps navigation; it does not invent axis location or engagement length.
Keep confirmed position notes separate from open grip questions.
Capture axis location, knurl zone, threaded engagement, and clearance to neighbors.
| Positioning field | What to record | Send with quote |
|---|---|---|
| Layout revision | Drawing controlling piercing-pin location | Yes |
| Pin axis / datum | Position relative to the assembly datum | Yes |
| Knurl grip zone | Length or diameter zone intended for hand grip | Yes |
| Threaded engagement note | Engagement or stop condition if shown | Yes |
| Neighbor clearance | Parts that limit knob swing or pin travel | Yes |
Do not invent hardness, piercing force, or material claims for blank cells.
A sample can show knurl feel and approximate knob envelope. Photograph orientation against a representative layout, mark observations to the revision, and list unverified axis dimensions.
Escalate samples that shift the axis or engagement relative to the drawing.
Distribute the same revision, positioning fields, quantities, destination, and open points. When axis location remains open, label it rather than inviting each quote to assume a different pin position.
Attach alternatives to the positioning question they answer.
Important: Do not release a purchase description for knurled knob piercing pin positioning when the controlling drawing, interface, or approval owner is still open; keep misfit risk visible in the RFQ. — Source: ISO standards catalogue.
This positioning checklist does not prove piercing force, fatigue life, torque capacity, corrosion performance, sealing, certification, or lifecycle. Those outcomes need product-specific evidence and the assembly owner’s validation plan.
Fit Boundary: pause when pin axis, knurl zone, or approval ownership is unclear.
After positioning inputs are ready, open the TNHO knurled knob piercing pin threaded stud. Navigation confirms a related knurled-knob piercing-pin threaded-stud destination; it does not replace layout dimensions or create unlisted lead times.
Send with quote / RFQ bullets:
– Layout revision and pin-axis datum
– Knurl grip zone and engagement note
– Neighbor clearance and open points
– Quantities and destination
Send the controlled drawing and RFQ inputs. For piercing-pin positioning navigation, open TNHO products then continue with Electrical Fasteners: Some Basic Information.
Confirm layout revision, pin axis, knurl grip zone, and approval owner.
No. Position must come from the controlled layout.
Include positioning fields, quantities, destination, and open points.
No. Performance needs project-specific evidence.
Pause when pin axis or knurl zone ownership is unclear.
Use the verified piercing-pin product route with the positioning package.
