DIN 7983 raised countersunk tapping screws wholesale supplier
XZ Fastener supplies DIN 7983 raised countersunk tapping screws for wholesale buyers, distributors, and assembly suppliers that need a partly countersunk seat with a rounded visible head. These screws are used in electrical covers, appliance panels, sheet metal housings, plastic components, and light assemblies where appearance and controlled seating both matter. Material, drive recess, point style, finish, small box packing, carton labels, barcode marks, and pallet method can be arranged according to order requirement. Buyers comparing related fastener products can send one complete purchasing list for review.
Quick Specs
What Buyers Should Know Before Sourcing DIN 7983 Raised Countersunk Tapping Screws
DIN 7983 raised countersunk tapping screws combine a countersunk seating area with a slightly rounded raised head. They are different from DIN 7982 fully countersunk screws, which are selected when a flatter finished surface is required. Wholesale buyers should confirm head profile, countersunk seat, pilot hole size, drive recess, material, finish, carton quantity, and installation torque before ordering.
These tapping screws normally require a prepared hole and are not the same as self drilling screws. The raised head can improve appearance on visible assemblies, but the mating part still needs a suitable countersink or seat. For private labels, special head details, or non-standard drawing items, XZ Fastener can review related custom fasteners. Buyers checking standard references may also use this DIN and ISO fastener standards guide.

Material and Grade Explanation
Carbon Steel
Carbon steel DIN 7983 screws are commonly selected for wholesale supply because they support practical tapping performance and flexible surface treatment. Case hardening can help the thread form into sheet metal, while controlled core toughness helps reduce breakage during installation. Hardness records and trial assembly checks can be supplied according to order requirement.
Stainless Steel
Stainless steel A2 and A4 options are used when corrosion resistance matters more than the tapping behavior of case-hardened carbon steel. Stainless tapping screws should be tested with the actual receiving material, especially in plastic bosses or harder sheet materials.
If the same wholesale order includes load-bearing bolts or stronger assemblies, buyers can review XZ Fastener’s high-strength fasteners and combine them with DIN 7983 screws for one supply plan.
Surface Finish Selection Guide
| Finish | Typical Wholesale Use | Selection Advice |
|---|---|---|
| Zinc plated | General indoor appliance, electrical, and sheet metal assemblies | Confirm blue white, white, yellow, or other finish color before production. |
| Чернение | Dark appearance for limited-corrosion applications | Usually needs oil protection and moisture-conscious packing. |
| Nickel plated | Cleaner appearance and selected decorative or electrical assemblies | Confirm surface brightness and appearance sample if needed. |
| Phosphate | Dark surface with oil retention | Corrosion resistance should be checked against storage and service conditions. |
| Custom coating | Project-specific color, corrosion, or handling requirement | Written coating requirements or samples help reduce approval risk. |
When the visible head finish matters for resale or assembled product appearance, compare available coated fasteners before confirming the wholesale batch.
Manufacturing and Quality Control
DIN 7983 raised countersunk tapping screws require stable wire selection, cold heading, raised countersunk head forming, recess forming, thread rolling, heat treatment, surface treatment, sorting, and packing. Because the head is visible in many applications, inspection should pay close attention to head shape, surface appearance, recess depth, thread condition, and coating consistency.
- Incoming wire material can be checked according to order requirement.
- Raised countersunk head profile, recess depth, and thread form should be monitored during production.
- Heat treatment and coating records can be supplied when required.
- Random checks may include dimensions, appearance, drive fit, and packing accuracy.
- Wholesale packing checks should cover quantity, small box labels, carton marks, pallet marks, and batch separation.
For private labels, barcode packaging, or special inspection plans, XZ Fastener’s customized service can help align wholesale details before order release.
Приложения
| Application Area | Why DIN 7983 Is Used | Important Check |
|---|---|---|
| Electrical covers | Raised countersunk head gives a neat visible finish with partial seating. | Confirm countersunk seat, coating, and head appearance. |
| Appliance panels | Useful where the screw head remains visible but should look controlled. | Check head fit, recess quality, and installation torque. |
| Plastic housings | Tapping thread can form engagement in selected plastic bosses. | Test boss design, pilot hole, screw length, and crack risk. |
| Light sheet metal assemblies | Suitable for prepared holes where appearance and seating both matter. | Do not replace engineered bolts without approval. |
When the same wholesale order includes screws, bolts, nuts, and washers, buyers can review XZ Fastener’s industrial bolts for compatible purchasing and shipment planning.

Yes. DIN 7983 screws can be supplied according to size list, material, finish, packing, and inspection requirements. Buyers should provide quantity by each size for accurate quotation and supply planning.
How is DIN 7983 different from DIN 7982?
DIN 7983 has a raised countersunk head with a rounded visible top. DIN 7982 is a countersunk style used when a flatter surface is required. The correct choice depends on appearance and seating requirements.
Are DIN 7983 screws self drilling screws?
No. DIN 7983 screws are tapping screws and usually require a prepared pilot hole. Self drilling screws have a drill point and use a different installation method.
Which material is commonly used for DIN 7983 tapping screws?
Carbon steel is common for general tapping performance and coating flexibility. Stainless steel A2 or A4 may be selected when corrosion resistance is more important.
Can XZ Fastener supply small boxes or private labels?
Small boxes, barcode labels, carton marks, inner bags, and pallet marks can be discussed according to order requirement. Packing details should be confirmed before production.
Can inspection documents be provided?
Inspection documents can be supplied according to order requirement. Buyers should state dimensional reports, material records, coating checks, sample approval, or third-party inspection needs before order confirmation.
