العربية ISO 4762 socket head cap screws bulk order manufacturer
XZ Fastener manufactures ISO 4762 socket head cap screws for bulk orders where buyers need compact head design, high clamp load, stable hex socket drive performance, and consistent lot packing for repeat assembly or distributor programs. These metric socket screws are used in machinery, tooling, automation equipment, frames, molds, fixtures, and maintenance assemblies. Alloy steel, carbon steel, and stainless steel options can be supplied with property class, thread length, surface finish, carton quantity, pallet method, and inspection documents according to order requirement. Buyers can send drawings, size lists, target finish, and annual quantity plans for factory review.
Quick Specs
What Buyers Should Know Before Sourcing ISO 4762 Socket Head Cap Screws
ISO 4762 socket head cap screws are used when a cylindrical head, internal hex drive, and strong clamping force are needed in limited space. Bulk order buyers should confirm diameter, pitch, length, thread length, property class, material, drive size, head dimensions, finish, carton weight limit, pallet method, and inspection documents before production. Drawings or approved samples are useful when the screw must fit existing counterbores.
If the same order includes washers, nuts, anchors, or other fastener products, XZ Fastener can review the complete list and quote related items together.
ISO 4762 is often compared with DIN 912 socket head cap screws. For bulk production, confirm the exact standard shown on the drawing and whether equivalent dimensions are acceptable before purchasing.

Material and Grade Explanation
Alloy Steel Class 12.9
Class 12.9 alloy steel is commonly used for high-strength machinery connections, tooling fixtures, molds, and automation equipment where high clamp load and compact head design are required. Hardness and surface protection should be confirmed with the application condition.
Class 8.8 and 10.9
Class 8.8 and 10.9 options can be supplied for general machinery, frames, brackets, and equipment assemblies. They may be selected when the joint does not require class 12.9 performance but still needs reliable metric socket fastening.
Stainless Steel A2 and A4
Stainless steel ISO 4762 screws are used where corrosion resistance is more important, such as food equipment frames, outdoor cabinets, marine-related hardware, and humid industrial environments.
Project Matching
For assemblies that combine socket cap screws with washers, nuts, and other high-strength fasteners, the material grade and finish should be checked as a complete joint package.
Surface Finish Selection Guide
| Finish | Typical Use | Bulk Order Comment |
|---|---|---|
| Black Oxide | Machine tools, molds, fixtures, indoor mechanical assemblies | Common for alloy steel socket cap screws; oil protection and packing should be confirmed. |
| Plain | Controlled storage, stainless steel supply, special customer treatment | Suitable when the buyer will apply its own coating or use stainless material. |
| Zinc Plated | General carbon steel screws for equipment and maintenance stock | Confirm coating thickness, color, and corrosion expectation before production. |
| Phosphate | Industrial screws needing darker appearance and oil retention | Often used with oil for controlled indoor applications. |
| Passivated Stainless | Stainless steel screws requiring cleaner surface condition | Recommended when corrosion resistance and surface cleanliness are important. |
For projects requiring multiple coatings, buyers can review coated fasteners and send the finish requirement together with the ISO 4762 size list.
Manufacturing and Quality Control
Manufacturing control for ISO 4762 socket head cap screws focuses on thread accuracy, head diameter, head height, hex socket depth, socket concentricity, hardness, surface finish, and packing separation. For bulk orders, stable lot control, consistent heat treatment, and clear item separation help reduce receiving errors and assembly interruptions.
Buyers comparing ISO, DIN, and metric fastener terminology can use the DIN and ISO fastener standards guide before sending the final inquiry.
Common Checks Before Shipment
- Thread gauge and thread length confirmation
- Head diameter, head height, and under-head surface inspection
- Hex socket size, depth, and recess condition review
- Hardness check for high-strength property classes
- Surface finish and visual sorting
- Carton quantity, labels, pallet marks, and packing list review
