DIN 915 牙尖紧定螺钉工厂
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 紧固件产品 can send drawings or size lists for factory review.

买家在采购DIN 915 凸端紧定螺钉之前应了解什么
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 高强度紧固件, check whether the drawing calls for DIN 915, an ISO equivalent, or a customer-specific point detail. The DIN和ISO紧固件标准指南 can help purchasing teams clarify standard references before sending an inquiry.

材质及牌号说明
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 工业螺栓, washers, and nuts, material compatibility and finish selection should be reviewed across the full assembly.
表面处理选择指南
- 黑色氧化物： Common for alloy steel socket set screws, often requested with light oil protection.
- 镀锌： Used when a brighter finish and moderate corrosion resistance are required for protected assemblies.
- 普通饰面： 适用于买方计划下游涂油、涂层或内部加工的情况。
- 不锈钢钝化： 当清洁外观和耐腐蚀性很重要时，可使用 A2 或 A4 不锈钢紧定螺钉。
- 其他涂料： Special finish requests can be reviewed with drawing, tolerance, thread fit, and application details.
制造和质量控制
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 定制紧固件 before placing a factory order.
应用领域
- 轴环、定位环、旋钮、滑轮、齿轮、手柄和调节部件。
- 固定螺钉点进入钻孔、凹槽或狭槽的组件。
- 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.
