Русский DIN 915 dog point set screws bulk order manufacturer
XZ Fastener manufactures DIN 915 dog point set screws for bulk orders that require headless socket fasteners, controlled cylindrical locating ends, and stable packing for repeated assembly use. The dog point is designed to enter a prepared hole, slot, or groove while reducing direct damage to the mating surface compared with sharper point styles. Material, strength class, finish, dog point diameter, point length, quantity per size, carton label, pallet method, and inspection documents can be supplied according to order requirement. Buyers comparing related fastener products can send one consolidated purchasing list for review.

What Buyers Should Know Before Sourcing DIN 915 Dog Point Set Screws
DIN 915 is selected when the end of the screw must locate into a prepared feature rather than simply press into a surface. The dog point supports repeat positioning, guided locking, and controlled stop functions in mechanical assemblies. Bulk order buyers should confirm dog point diameter, dog point length, total length, thread tolerance, finish, carton unit, and pallet requirements before production confirmation.
For purchasing programs that include socket set screws and other high-strength fasteners, separate each line by standard, size, material, finish, and packaging method. If drawings reference DIN or ISO details, the DIN and ISO fastener standards guide can help clarify standard descriptions before quotation.

Material and Grade Explanation
Alloy steel is commonly requested for DIN 915 dog point set screws when buyers need higher hardness, stable socket engagement, and repeatable locating performance. Class 45H is a frequent requirement for socket set screws, but the final grade should follow the drawing, load condition, finish, and end-use environment. Carbon steel may be considered for lighter duty applications, while stainless steel A2 or A4 can be supplied for corrosion-sensitive assemblies.
When the same bulk order includes set screws, industrial bolts, washers, and nuts, material compatibility and surface treatment should be checked across the full assembly list.
Surface Finish Selection Guide
- Black oxide: Common for alloy steel socket set screws and often requested with light oil protection.
- Zinc plated: Used when a brighter appearance 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, thread tolerance, coating thickness, and application details.
Manufacturing and Quality Control
Manufacturing control for DIN 915 dog point set screws focuses on thread rolling, socket forming, dog point diameter, dog point length, heat treatment, surface finish, and packing consistency. The dog point should be controlled carefully so it can locate into the mating feature without causing assembly interference. XZ Fastener can arrange thread gauge checks, socket fit review, point geometry inspection, finish inspection, and lot-based packing records according to order requirement.
If the bulk order requires a special dog point length, chamfer, radius, end flatness, or non-standard size, include the drawing with the inquiry. For point details or packing outside normal standards, buyers can also review custom fasteners before confirming production.
تطبيقات
- Shaft collars, locating rings, knobs, pulleys, gears, handles, and adjustment components.
- Assemblies where the set screw point enters a drilled hole, groove, or slot.
- Machinery fixtures requiring repeatable positioning with less shaft damage than cone point screws.
- Distributor inventory, maintenance kits, repair stock, and metric socket set screw assortments.
- Bulk assembly programs requiring stable carton labels, batch separation, and repeat purchasing records.
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 bulk 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 bulk orders?
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.
