Countersunk Head Self Drilling Screws
DIN 7504 P Stainless Steel Self Drilling Screws for Flush Sheet Metal Assembly
DIN 7504 P Countersunk Head Self Drilling Screws combine an integrated drilling point, tapping thread and cross-recessed approximately 80° flat head for one-step metal fastening with a flush or near-flush finish. DIN 7504 P is the primary purchasing designation; ISO 15482 is the corresponding international reference.
Product Overview
DIN 7504 P combines a self-drilling point, tapping thread and countersunk head. The correct sequence is DRILL → THREAD → COUNTERSINK SEATING. Unlike DIN 7504 N pan-head screws, its head enters a compatible countersunk interface instead of remaining prominently above the component.
The approximately 80° countersunk geometry is selected where a smooth surface, panel clearance or low projection is required. The mating metal countersink should match the specified head; a generic 90° interface can cause edge-only contact, a proud head, localized pressure or sheet deformation.
Buyers should specify DIN 7504 P, ST diameter, total screw length, PH or PZ, 410/304/316 material, drill point, top and supporting materials, individual and total thickness, countersink geometry, quantity and drawing where required.
Technical Specifications
Countersunk Fit, Drill Point & Material Thickness Selection
410, 304 & 316 Stainless Steel Options
Size, Drive & OEM Manufacturing
ST2.9–ST6.3 and approximately 9.5–50 mm standard-style lengths; important commercial sizes include ST3.5, ST4.2, ST4.8, ST5.5 and ST6.3.
PH or PZ cross recess with approximately 80° standard-style head. Products with different head angle, diameter or recess are described as custom, not falsely retained as DIN 7504 P.
Provide size, length, drive, material, head/countersink requirement, upper/supporting materials and thicknesses, total drilling stack, quantity and drawing/sample.
Inner bags, boxes, export cartons, pallets, customer labels, part numbers and authorized private-label packaging.
Countersunk Fit, Drill Point & Quality Inspection
Inspection verifies thread, head diameter/height/angle/profile, recess geometry, overall length measured from top of head, drill-point diameter/length/cutting edges/flutes, material and applicable heat treatment. Representative fit and drilling tests may evaluate thread formation, flushness, countersink contact, deformation and recess condition. Documentation may include MTC, raw-material, dimensional, hardness, product and actually performed functional reports. No universal RPM, torque, drilling time or maximum thickness is claimed.
Applications
One-step drilling with flush or near-flush finishing in compatible industrial metal assemblies.
Low-profile fastening where protruding heads are undesirable.
Selected covers, panels and fabricated electrical components requiring a smooth surface.
Compatible joints completed by drilling, thread forming and fastening in one operation.
Metal brackets and housings where surface clearance is limited.
Specified DIN 7504 P size, countersunk geometry, drive, grade and drilling conditions.
Frequently Asked Questions
What is DIN 7504 P?
DIN 7504 P is a widely used purchasing designation for cross-recessed countersunk-head self-drilling screws with tapping thread. ISO 15482 is the corresponding international reference.
What is the difference between DIN 7504 P and DIN 7982?
DIN 7504 P has an integrated drill point; DIN 7982 refers to countersunk self-tapping screws without the same self-drilling point.
What head angle is used for DIN 7504 P?
Applicable DIN 7504 P / ISO 15482 style products use an approximately 80° countersunk head, requiring a compatible mating countersink.
What sizes can VALTOR supply?
Common sizes range from ST2.9–ST6.3 with approximately 9.5–50 mm standard-style lengths depending on diameter.
Should I choose 410, 304 or 316 stainless steel?
410 is primary where drill-point hardness matters. 304 and 316 provide higher corrosion resistance, but drilling suitability must be confirmed for the actual substrate and thickness.
