العربية ISO 14583 hexalobular pan head screws bulk order manufacturer
XZ Fastener manufactures ISO 14583 hexalobular pan head screws for bulk orders where buyers need six-lobe drive engagement, clean pan head appearance, stable lot control, and practical packing for assembly lines or distributor replenishment. These metric machine screws are selected when better torque transfer and reduced cam-out are required compared with common cross recess screws. Carbon steel, alloy steel, and stainless steel options can be supplied with property class, thread length, drive size, surface finish, carton quantity, pallet method, label format, and inspection documents according to order requirement. Send size lists, packing needs, drawings, and annual quantity plans for quotation review.
Quick Specs
What Buyers Should Know Before Sourcing ISO 14583 Hexalobular Pan Head Screws
ISO 14583 defines a pan head machine screw with a hexalobular internal drive. The head gives a neat external appearance, while the six-lobe recess supports stable torque transmission during repeated assembly. When replacing cross recessed pan head screws, buyers should confirm head diameter, head height, recess size, thread pitch, drive tool compatibility, and whether the application requires full thread or a specific thread length.
For drawings that reference several standards in one assembly, buyers can compare basic standard logic through the DIN and ISO fastener standards guide. This is especially useful when a purchasing list includes ISO socket screws together with DIN nuts, washers, or hex bolts.

Material and Grade Explanation
Carbon steel ISO 14583 screws are often selected for controlled indoor assembly, equipment panels, and cost-sensitive industrial products. Alloy steel options are suitable where higher strength or black oxide appearance is needed. Stainless steel A2 and A4 options are used when corrosion resistance or cleaner appearance is required.
Carbon Steel and Alloy Steel
For bulk order projects, carbon steel fasteners can be supplied with different property classes and finishes. Buyers should confirm whether the screw needs class 4.8 for general assembly, class 8.8 for higher clamping performance, or a project-specific mechanical property.
Stainless Steel
Stainless steel A2 is common for clean indoor or mildly corrosive environments. Stainless steel A4 can be considered for higher corrosion exposure. When stainless screws are assembled into stainless threads, lubricant or anti-galling practice may be required by the application.
Surface Finish Selection Guide
The finish should be chosen according to assembly environment, appearance, corrosion exposure, and drive engagement. XZ Fastener can review coating requirements together with thread tolerance and recess dimensions so the final screw remains practical for installation.
| Finish | Typical Use | Procurement Comment |
|---|---|---|
| Zinc Plated | General equipment, panels, electrical housings | Common economical option; color and salt spray requirement should be confirmed. |
| Black Oxide | Machinery parts, instruments, darker visual assemblies | Often used with oil protection; suitable where appearance and controlled fit are important. |
| Nickel Plated | Decorative or clean hardware applications | Available upon request when brighter appearance is needed. |
| Passivated Stainless | Stainless steel screws for clean or corrosion-exposed assemblies | Confirm A2 or A4 material before finish selection. |
| Special Coating | Project-specific corrosion or friction requirement | Review through coated fasteners when the project needs non-standard finish control. |
Manufacturing and Quality Control
For bulk order manufacturing, stable head forming, clean recess geometry, thread accuracy, and packing separation matter as much as the material grade. XZ Fastener reviews the drawing, sample, or purchasing description before production so screw form, drive size, finish, and labels can match the buyer’s assembly needs.
Manufacturing Focus
- Cold forming or machining route selected according to size and order requirement
- Controlled pan head diameter, height, and rounded top appearance
- Hexalobular recess formed for reliable tool engagement
- Thread rolling or thread processing based on material and size
- Finish process selected to reduce burrs, blocked recesses, and thread fit issues
Inspection Focus
- Dimensional checks for diameter, length, head form, and thread pitch
- Drive gauge fit and recess depth control
- Hardness or mechanical property review when required
- Surface appearance, coating coverage, and mixed-size prevention
- Carton marks, labels, pallet method, and batch traceability information according to order requirement
Projects requiring drawing-based adjustments, special material, special drive depth, or private packing can be reviewed through XZ Fastener’s custom fasteners support.
Applications
ISO 14583 hexalobular pan head screws are used where a neat pan head, stable driver engagement, and repeatable installation are needed. They are especially practical in medium-volume and high-volume assembly lines.
