Match pilot-hole preparation to the thread system, workpiece and agreed acceptance requirement.
The M6 row has L 80 mm, Lc 15 mm, d 4.5 mm and k 3.4 mm. At M3, the square dimension is not specified in the source entry; use the interface drawing for a holder decision.

PRODUCT SELECTION
Application, Chip Path & Selection Limits
Match the component and operation
Review the reduced-shank arrangement with the holder and available component access. The straight flute cutting form still needs a separate assessment of material, hole type and chips.
Check the operating boundary
A smaller shank is not proof of automatic through-part clearance or a guaranteed full-thread depth. Specify pitch and required engagement; nominal sizes in the table do not provide a complete thread callout.
PRODUCT SELECTION
Compare the Adjacent Product Families
| Product family | Selection boundary to review |
|---|---|
| DIN 371 HSS Straight Flute Machine Tap | Keep the DIN 371 shank dimensions explicit when a customer asks for a straight-flute replacement. |
| DIN 376 HSS Spiral Flute Machine Tap | Keep the reduced-shank blind-hole tap separate from DIN 371 stock with the same thread label. |
| DIN 376 HSS Spiral Point Machine Tap | Separate reduced-shank reach and forward chip clearance in a DIN 376 point-tap enquiry. |
Keep the selected family, thread designation and dimensional reference together. Shared nominal sizes or drive shapes do not establish interchangeability.
WORKSHOP & SUPPLIER REVIEW
Workshop, Material Handling & Order Organisation
Reduced-shank straight flute orders need a complete drive-dimension reference. Use the supplier review to distinguish the DIN 376 interface from DIN 371 and to resolve any unlisted small-size square dimension.
Bar-stock handling
Carry the HSS / HSS-Co requirement with the item drawing when discussing material preparation for this range.
Component feed and transfer
Keep the approved item identity and dimensional revision with components during order discussions. Use the exact thread and drive dimensions to distinguish similar tools.
Plan the order around the approved item
- Define the thread and application using this product’s selection table.
- Compare the tool interface and cutting geometry with the sample or drawing.
- Agree sample acceptance, quantities by size and the requested pack arrangement.
- Reference the same approved item and revision for replenishment.
QUALITY & SAMPLE ACCEPTANCE
Quality Review for the Selected Specification
The reduced-shank interface and its transition to the working section deserve sample review. Where a square dimension is not given, agree the drawing rather than treating a blank as a zero-width drive.
Use the following items to define the sample and order acceptance brief.
| Review item | What to agree | Procurement risk addressed |
|---|---|---|
| Thread identification | Nominal size, required pitch and finished-thread requirement | Avoid the wrong thread family or pitch |
| Dimensions and holding | The M6 row has L 80 mm, Lc 15 mm, d 4.5 mm and k 3.4 mm. At M3, the square dimension is not specified in the source entry; use the interface drawing for a holder decision. | Avoid holder mismatch, insufficient reach or unintended substitution |
| Geometry / set identity | The reduced-shank interface and its transition to the working section deserve sample review. Where a square dimension is not given, agree the drawing rather than treating a blank as a zero-width drive. | Avoid the wrong cutting form or incomplete member sequence |
| Sample acceptance plan | Agree the reference drawing, acceptance method and sampling requirement for the application | Make sample approval and repeat-order review refer to the same item |
PROCUREMENT & REPLENISHMENT
Packaging, Custom Requests & Bulk Purchasing
Keep the packing brief specific
Separate DIN 376 straight flute stock from both DIN 371 and DIN 376 spiral forms. For larger-size replenishment, keep the actual shank and square values in the SKU record instead of assuming they increase at each nominal size.
Marking, packs & repeat orders
Request DIN 376 straight flute identification and quantity by nominal size/pitch. Keep the approved interface drawing with any size whose source table does not specify a square dimension.
Turn the selection into a clear purchasing list
Specify the reduced-shank straight-flute family without losing the drive dimensions on the order.
SELECTION & BUYER QUESTIONS
Product Questions
What is the main DIN 376 straight-flute distinction?
This is the reduced-shank dimensional family, with its own d and k values. The M6 entry has a 4.5 mm shank and 3.4 mm square.
Does this range go beyond DIN 371 M10?
The listed DIN 376 range runs to M24, while this catalogue’s DIN 371 straight flute range ends at M10. Choose the actual required size and dimensions.
Why is the M3 square dimension shown as a dash?
The source does not specify a value for that entry. It must not be interpreted as zero; confirm the interface with the required drawing.
Is DIN 376 enough to specify the thread pitch?
No. The source table lists nominal M sizes without pitch. Add the pitch and finished-thread requirement to the order.
Can a reduced shank guarantee passage through the component?
No. Compare every relevant diameter, shoulder, clamping length and access restriction with the component and holder drawings.
How should a DIN 376 straight flute sample be identified?
Use size/pitch, straight flute, L/Lc/d/k and requested material. Keep it distinct from DIN 376 spiral flute and spiral point samples of the same nominal size.
