Quick Specs
What Buyers Should Know Before Sourcing ISO 7380 Button Head Socket Screws
ISO 7380 button head socket screws are selected when an assembly needs a rounded, low-profile head and an internal hex drive. Compared with cylindrical socket head cap screws, the button head form gives a smoother visible surface but has different drive engagement and load considerations. Buyers should confirm head diameter, head height, socket size, thread length, and seating surface before placing repeat wholesale orders.
For broader purchasing programs, XZ Fastener can quote related standard fasteners and matching items in the same shipment. This helps distributors combine ISO 7380 button head screws with washers, nuts, bolts, and special packing requirements.
Wholesale Sourcing Notes
- Confirm whether the order requires full thread or partial thread.
- Specify hex socket tolerance, burr control, and head appearance if the screw is visible after installation.
- State whether material traceability or dimensional inspection records are required.
- For shelf stock, define inner box quantity, outer carton quantity, label content, and mixed-size packing rules.
Common Purchasing Descriptions
Wholesale buyers may describe this product as ISO 7380 button head socket screws, button head Allen screws, low head socket screws, metric button head cap screws, or hex socket button head screws. For accurate quotation, include the exact diameter, pitch, length, material, property class, finish, and packing style.
Many buyers consolidate multiple metric items in one inquiry. Along with ISO 7380 screws, purchasing lists may also include DIN 933 full thread hex bolts, Grade 8.8 carbon steel hex bolts, metric hex head bolts, zinc plated DIN 933 bolts, black oxide DIN 933 bolts, and hot dip galvanized DIN 933 bolts. Related industrial bolts can be reviewed when a project requires both socket screws and hex head fasteners.
Detailed Specifications Table

Material and Grade Explanation
Alloy Steel and Carbon Steel
Alloy steel and carbon steel ISO 7380 button head socket screws are used where strength, cost control, and stable assembly performance are important. Property classes such as 8.8 and 10.9 can be discussed according to the application. Heat treatment, hardness, and thread fit should match the intended installation load.
Stainless Steel A2 and A4
Stainless steel A2 and A4 options are often selected for equipment, panels, light outdoor use, and assemblies exposed to moisture. A4 stainless steel can be considered when stronger corrosion resistance is needed. Passivation and clean packing can be supplied according to order requirement.
When buyers compare button head socket screws with other fastener products, the final choice should consider head clearance, tool access, tightening method, seating surface, and the required appearance after installation.
Surface Finish Selection Guide
| Finish | Typical Use | Buyer Consideration |
|---|---|---|
| Black Oxide | Machinery, tools, fixtures, indoor assemblies | Provides dark appearance; oil protection and packing method should be confirmed. |
| Zinc Plated | General industrial assembly and distributor stock | Common finish for carbon steel screws; color and salt spray target can be discussed. |
| Nickel Plated | Decorative or controlled appearance applications | Useful when a brighter surface is needed; check application environment before selection. |
| Phosphate | Industrial components requiring oil retention | Often used with protective oil; storage conditions should be considered. |
| Plain Stainless or Passivated | Stainless steel assemblies and moisture-exposed equipment | Passivation can be requested for improved surface cleanliness. |
For orders that combine socket screws with coated bolts or nuts, XZ Fastener can also support coated fasteners according to project requirement.
Manufacturing and Quality Control
Manufacturing control for ISO 7380 button head socket screws should focus on cold forming quality, head diameter, head height, head radius, socket depth, socket concentricity, thread accuracy, material grade, heat treatment, surface finish, and final packing. For visible installations, buyers should also pay attention to head marks, surface scratches, burr control, and consistent coating color.
Inspection items can include dimensional checks, thread gauge checks, hardness testing, visual inspection, coating inspection, and packing verification. When a buyer needs formal reference information, the DIN and ISO fastener standards guide is a useful starting point for standard selection discussions.
Aplicaciones
- Machine guards, cover plates, and access panels
- Automation equipment, robotics frames, and fixture systems
