Quick Specs
What Buyers Should Know Before Sourcing DIN 912 Socket Head Cap Screws
DIN 912 socket head cap screws are selected when a cylindrical head, internal hex drive, high clamp load, and compact tool access are needed. Before sourcing, buyers should confirm diameter, length, thread pitch, thread length, strength class, material, finish, socket size, and packaging format. XZ Fastener supplies related hex socket head cap screws for machinery and equipment applications where consistent dimensions and drive quality are important.
For export orders, packaging and documentation are as important as product dimensions. Carton weight, pallet size, moisture protection, shipping marks, and receiving labels should be confirmed early, especially for distributors and OEM warehouses.

Material and Grade Explanation
Alloy steel DIN 912 socket head cap screws are commonly used for high-strength machinery, molds, tooling, and equipment assemblies. Class 12.9 black oxide screws are often selected for compact, high clamp-load joints, while class 8.8 and 10.9 may be suitable for general equipment. Stainless steel 304 and 316 socket screws are used when corrosion resistance is more important than maximum tensile strength.
For export purchasing, buyers should align material grade with the application and destination requirements. XZ Fastener’s fastener material selection guide can help compare load, corrosion exposure, and working conditions before confirming the final order.
Surface Finish Selection Guide
Black Oxide
Common for alloy steel socket head cap screws used in machinery, tooling, and mold assemblies. Oiling and moisture-resistant packing should be considered for export shipment.
Plain Alloy Steel
Used when buyers require further processing or their own rust prevention. Storage and transit protection should be confirmed before shipment.
Zinc Plated
Suitable for general equipment and indoor assemblies. For high-strength screws, plating process and hydrogen embrittlement risk should be discussed before production.
Dacromet / Geomet
Can be considered for stronger corrosion resistance on selected high-strength fasteners. Coating thickness, socket cleanliness, and thread fit should be checked.
Nickel Plated
Used for bright appearance, wear resistance, and some equipment applications. Cosmetic acceptance requirements should be agreed before production.
Stainless Passivation
Available for stainless steel 304 and 316 screws according to order requirement. Grade selection should match the working environment.
For a practical comparison of coating options, buyers can review the black oxide vs zinc plated fastener guide before choosing a finish for export inventory or project use.
Manufacturing and Quality Control
DIN 912 socket head cap screw production may include wire preparation, cold heading, socket forming, thread rolling, heat treatment, surface treatment, sorting, inspection, and packing. For high-strength alloy steel screws, heat treatment and surface condition should be controlled carefully. For stainless steel screws, thread accuracy, head dimensions, socket fit, and surface cleanliness are important for assembly reliability.
Quality control can include head diameter, head height, socket depth, thread length, pitch, hardness, tensile strength, coating thickness, and visual checks. Buyers can review XZ Fastener’s thread inspection methods before listing inspection requirements in the purchase order.
