العربية DIN 913 flat point set screws exporter
XZ Fastener exports DIN 913 flat point set screws for importers, distributors, and machinery assembly buyers that need headless socket fasteners with stable positioning and export-ready packing. These screws are used where the point should press against a mating part without the deeper indentation made by cup or cone points, such as collars, fixtures, adjustment blocks, knobs, machine slides, and locating parts. Material, strength class, finish, thread size, socket details, carton marks, pallet method, and inspection documents can be supplied according to order requirement. Buyers comparing related fastener products can send one complete inquiry list.

Quick Specs
What Buyers Should Know Before Sourcing DIN 913 Flat Point Set Screws
DIN 913 set screws use a flat point instead of a cup, cone, or dog point. The flat end spreads contact pressure over a small flat surface, making it useful when the buyer wants holding or positioning without aggressive biting into the mating shaft or part. If your engineering team compares DIN and ISO references, the DIN and ISO fastener standards guide can help clarify standard naming and drawing references.
For export purchasing, the screw details and the packing details both matter. Buyers should confirm shaft material, torque expectation, socket engagement, thread pitch, finish, carton label, and pallet mark before shipment. XZ Fastener can review DIN 913 screws together with related high-strength fasteners when assemblies require consistent strength and material control.

Detailed Specifications Table
| Item | Typical Supply Detail | Export Purchasing Notes |
|---|---|---|
| Standard | DIN 913 | Confirm flat point set screw requirement against the drawing or assembly list. |
| Head Style | Headless set screw | Suitable where the fastener must sit inside a tapped hole without a projecting head. |
| Drive | Internal hex socket | Socket size and depth affect tightening torque and tool engagement. |
| Point Type | Flat point | Designed for positioning and pressure contact with less aggressive surface bite than cup point. |
| Thread | Metric full thread | Check thread pitch and tolerance when used with precision machined parts. |
| Size Range | Common metric sizes such as M3 to M20 | Actual range depends on material, finish, and order quantity. |
| Material | Alloy steel, carbon steel, stainless steel | Alloy steel is common for higher strength; stainless steel is used for corrosion resistance. |
| Surface Finish | Black oxide, zinc plated, plain, stainless passivated options | Finish should match storage conditions, installation environment, and appearance needs. |
| Packing | Bulk carton, inner bag, small box, pallet packing | Export orders need clear item labels, carton marks, and pallet layout. |

Material and Grade Explanation
Alloy steel DIN 913 flat point set screws are commonly supplied in class 45H when the assembly needs stronger thread strength and reliable socket performance. This choice is often used in machine tools, collars, fixtures, locating parts, adjustment screws, and compact mechanical equipment.
Stainless steel A2 is often selected for indoor equipment and mildly humid environments. A4 stainless steel may be considered where corrosion exposure is higher. When the export order includes mating components, XZ Fastener can also review compatible industrial nuts and flat washers for the same purchasing plan.
Surface Finish Selection Guide
Black oxide is widely used for alloy steel DIN 913 set screws because it is common in machinery assemblies and provides a dark surface. Zinc plating may be selected for general industrial use where basic corrosion protection is required. Plain finish may be used when the buyer has a post-treatment process or controlled indoor storage.
For humid, outdoor, or chemical environments, stainless steel may be more suitable than coated carbon steel or alloy steel. If a shipment includes set screws, bolts, nuts, and washers, XZ Fastener can review related coated fasteners to keep finish requirements consistent across the order.
Manufacturing and Quality Control
DIN 913 flat point set screws require careful control of thread rolling, socket forming, point machining or forming, heat treatment when required, surface finish, and packing. The flat point must be clean and consistent because burrs or uneven contact faces can affect positioning and may damage the mating part. For export supply, carton separation and label accuracy are also important for warehouse receiving and downstream distribution.
Common Control Points
- Confirm DIN 913 standard, diameter, length, thread pitch, socket size, and flat point requirement.
- Check socket depth and hex engagement to reduce tool stripping during installation.
- Review flat point face, edge condition, and concentricity for stable contact.
- Verify hardness or material requirement when higher tightening force is required.
- Separate cartons by size, material, finish, lot number, customer item code, and pallet number.
For special point form, unusual length, private packing, or drawing-based parts, buyers can review custom fasteners and send drawings for feasibility checking.
Applications
| Application Area | Why DIN 913 Is Used | Procurement Note |
|---|---|---|
| Adjustment blocks | Flat point provides pressure contact for positioning and alignment. | Confirm whether repeated adjustment will occur. |
| Machine slides | Headless design fits compact assemblies without a projecting head. | Check thread tolerance and socket engagement. |
| Collars and knobs | Flat point can hold position with less aggressive bite than cup point. | Review shaft material and acceptable surface marking. |
| Fixtures and tooling | Useful for repeatable locating, stops, and pressure adjustments. | Confirm hardness and finish before production. |
| Instrument and equipment parts | Small headless design supports compact assemblies and clean external surfaces. | Stainless steel may be considered for corrosion-sensitive equipment. |

FAQ
What is a DIN 913 flat point set screw used for?
It is used for positioning, adjustment, locating, and holding parts such as collars, knobs, fixtures, machine slides, and stops where a flat contact face is preferred.
How is DIN 913 different from DIN 916?
DIN 913 has a flat point, while DIN 916 has a cup point. DIN 913 is often chosen when the buyer wants less aggressive surface bite than a cup point set screw.
What material is common for DIN 913 set screws?
Alloy steel class 45H is common for higher strength. Carbon steel and stainless steel A2 or A4 options can also be reviewed according to order requirement.
Is black oxide suitable for DIN 913 flat point set screws?
Black oxide is widely used for alloy steel set screws in indoor machinery applications. For humid or corrosive environments, stainless steel or another finish should be considered.
What information is needed for a DIN 913 export quotation?
Please provide diameter, length, material, strength class, finish, quantity, packing method, destination, and inspection requirements. A drawing is helpful when socket depth or point face is controlled.
Can XZ Fastener supply DIN 913 screws with other fasteners?
Yes. DIN 913 set screws can be reviewed together with bolts, nuts, washers, and other standard fasteners for consolidated export purchasing and coordinated packing.
