DIN 912 Stainless Steel Socket Head Cap Screws
Youjia Metals supplies stainless steel socket head cap screw inquiries for industrial equipment, machinery, OEM assemblies, solar mounting, and reviewed marine or architectural projects. The pictured screw has a cylindrical head and an internal hex drive; it is not a countersunk flat-head screw.
Head Form and Standard
DIN 912 is a withdrawn legacy reference for socket head cap screws; ISO 4762 is the related current reference. Specify the exact dimensional requirements before ordering. Countersunk and button-head screws are separate designs and are reviewed under their own specifications, not described as DIN 912 head variants.
Material and Technical Requirements
| Material | SS304 / SS316 options reviewed for the application |
|---|---|
| Published Diameter Range | M2–M48; individual size and length availability confirmed in quotation |
| Thread | Metric coarse or fine requests; pitch, length, and tolerance specified separately |
| Head / Drive | Cylindrical socket cap head / internal hex |
| Property Class | A2-70 requests reviewed separately from SS304 material designation; required mechanical properties and documents must be specified |
| Finish | Uncoated stainless, polished, or passivated requests reviewed for the order |
| Custom Work | Non-standard length, thread, and drawing-based geometry; STP / DWG files accepted for review |
The former listing included ±0.005 mm thread precision and a −50°C to +120°C operating range. These are not universal product guarantees: tolerance and temperature requirements must be assessed and confirmed for the actual material, dimensions, load, and application.
Application and Installation
Inquiries can be reviewed for machine tools, transmission equipment, vibrating equipment, vehicle assemblies, mounting brackets, cable-terminal assemblies, renewable-energy equipment, furniture, and building hardware. Safety-critical structures, lifting systems, offshore installations, and vehicle components require their own engineering approval and applicable documents.
Use a compatible hex key or bit and the specified installation torque. A socket drive does not make a joint vibration-proof or prevent loosening, fracture, or thread stripping. Select any required locking method, mating material, lubrication, and inspection criteria for the joint.
SS304 and SS316 are not corrosion-proof. Material selection depends on exposure, temperature, load, and maintenance. Stainless threads can gall; specify appropriate assembly controls rather than assuming the finish prevents galling.
OEM Supply and Quality Documents
Send dimensions, material, property class, finish, quantity, required tests, packaging, and destination. Material identification, dimensional checks, mechanical tests, traceability, RoHS or REACH documentation, samples, warranty terms, and lead time are confirmed for the order. No unverified customer partnership, blanket compliance, free-sample offer, or 12-month warranty is claimed.
Frequently Asked Questions
Are DIN 912 screws countersunk?
No. The pictured DIN 912-style product is a cylindrical socket head cap screw. Request a separate countersunk design if your assembly requires a flush head.
Does SS304 automatically mean A2-70?
No. Specify the material and required mechanical property class separately, along with the verification documents.
Can you review non-standard dimensions?
Yes. Send an STP or DWG drawing and full requirements for technical review and quotation.
