Русский DIN 915 dog point set screws factory
XZ Fastener manufactures DIN 915 dog point set screws for buyers who need headless socket fasteners with a controlled cylindrical locating end. The dog point is suitable when the screw must enter a hole, slot, groove, or prepared seat while reducing direct damage to the mating shaft compared with sharper point styles. Material, strength class, finish, point diameter, point length, thread size, packing, and inspection details can be supplied according to order requirement. Buyers comparing related fastener products can send drawings or size lists for factory review.

What Buyers Should Know Before Sourcing DIN 915 Dog Point Set Screws
DIN 915 is selected when the screw end needs to locate into a hole or groove rather than create a sharp bite. The dog point can support repeat positioning, stop functions, and guided locking in assemblies where shaft surface damage must be reduced. Buyers should confirm dog point diameter, dog point length, thread length, and the mating hole or slot size before placing a factory order.
For projects that include socket set screws and other high-strength fasteners, check whether the drawing calls for DIN 915, an ISO equivalent, or a customer-specific point detail. The DIN and ISO fastener standards guide can help purchasing teams clarify standard references before sending an inquiry.

Material and Grade Explanation
Alloy steel is commonly used for DIN 915 dog point set screws when buyers need higher hardness, stable socket engagement, and reliable locating performance. Class 45H is a frequent requirement for socket set screws, but final grade selection should follow the drawing, service load, and assembly environment. Carbon steel may be suitable for lighter duty applications, while stainless steel A2 or A4 can be supplied for corrosion-sensitive parts.
When a purchasing program combines set screws with industrial bolts, washers, and nuts, material compatibility and finish selection should be reviewed across the full assembly.
Surface Finish Selection Guide
- Black oxide: Common for alloy steel socket set screws, often requested with light oil protection.
- Zinc plated: Used when a brighter finish and moderate corrosion resistance are required for protected assemblies.
- Plain finish: Suitable when the buyer plans downstream oiling, coating, or internal processing.
- Stainless passivation: Available for A2 or A4 stainless steel set screws when clean appearance and corrosion resistance matter.
- Other coatings: Special finish requests can be reviewed with drawing, tolerance, thread fit, and application details.
Manufacturing and Quality Control
Factory control for DIN 915 dog point set screws focuses on thread rolling, socket forming, controlled dog point diameter, dog point length, heat treatment, surface finish, and clean packing. The dog point must be consistent enough to locate into the mating feature without creating assembly interference. For production orders, XZ Fastener can arrange thread gauge checks, socket fit review, point geometry inspection, surface appearance checks, and lot-based packing control.
If your drawing requires a special dog point length, chamfer, radius, end flatness, or non-standard dimension, include it with the inquiry. For non-standard point geometry or customized packing, buyers can also review custom fasteners before placing a factory order.
تطبيقات
- Shaft collars, locating rings, knobs, pulleys, gears, handles, and adjustment parts.
- Assemblies where the set screw point enters a drilled hole, groove, or slot.
- Machinery fixtures requiring repeatable positioning with less shaft surface damage than cone point screws.
- Maintenance kits, repair stock, and distributor inventory for metric socket set screw sizes.
- Industrial equipment programs requiring consistent labels, batch separation, and repeatable factory supply.
How to Get a Faster Quotation
To receive a faster quotation, send diameter, total length, dog point diameter, dog point length, material, grade or hardness class, finish, quantity per size, packaging method, destination country, and inspection requirements. A drawing is especially helpful for DIN 915 because the dog point must fit the mating hole, groove, or slot correctly.
For orders that include multiple finishes, state which items need black oxide, zinc plating, plain finish, stainless steel, or other treatment. If the order also includes coated fasteners, separate finish requirements by item. To discuss order details, contact XZ Fastener with your purchasing file.
أسئلة متكررة
What is a DIN 915 dog point set screw used for?

How is DIN 915 different from DIN 914 and DIN 916?
DIN 915 has a cylindrical dog point for locating into a prepared feature. DIN 914 has a cone point for sharper contact, while DIN 916 has a cup point that can bite into a mating surface.
Can DIN 915 dog point set screws be supplied in class 45H?
Yes, alloy steel class 45H is a common requirement for socket set screws. Final supply should follow the drawing, application, finish, and purchase order requirement.
Which dimensions are most important for DIN 915 factory production?
In addition to thread diameter and total length, buyers should confirm dog point diameter, dog point length, socket size, thread tolerance, and any chamfer or end detail shown on the drawing.
Which finishes are commonly requested for DIN 915 set screws?
Black oxide is common for alloy steel set screws. Zinc plated, plain, stainless passivated, or other finishes can be supplied according to order requirement and application conditions.
What should be included in a quotation request?
Please send size list, material, grade, finish, quantity, packaging, inspection requirements, destination country, and drawings if the dog point dimensions are controlled.
