Stainless Steel DIN 914 Cone Point Set Screw

Wanluo factory direct-sale Stainless Steel DIN 914 Cone Point Set Screw. The entire machine adopts a headless integrated structure. After installation, it can be completely hidden inside the workpiece, without any protruding structures, and will not interfere with the operation of the equipment, the sliding of components, or the appearance structure.

Why choose it?

The product is produced in full accordance with German industrial standard tolerances. It is formed through high-precision cold forging and integrated hardening treatment. The overall hardness is high and the deformation rate is extremely low. The inner wall of the standard internal hexagonal hole is smooth and regular, suitable for precision internal hexagonal tools. It can withstand high torque locking and is not prone to cracking or slipping. The rolled formed metric full-threaded tooth profile is dense and uniform. The thread engagement is smooth and the positioning is precise. Combined with a high-hardness cone tip, it can firmly bite into the positioning recess of the workpiece, fundamentally solving common faults such as shaft body displacement, component loosening, and positioning failure during the long-term operation of the equipment. It is suitable for various mechanical working conditions that require precise calibration and long-term stable positioning.

Product application

1. Anti-rotation positioning of the transmission shaft and the rotating shaft

Our Stainless Steel DIN 914 Cone Point Set Screw is widely used for the circumferential fixation of various mechanical transmission shafts, core shafts, and round rod components. By using the cone tip to bite into the preset concave points on the shaft body, a rigid locking position is formed, preventing the shaft from rotating, shifting, or deviating in angle during equipment operation, ensuring the stable operation accuracy of the transmission structure.

2. Locking and fixing of gears, sprockets, and synchronous wheels

Suitable for the locking and fixation of gears, sprockets, synchronous wheels, and shaft bodies, replacing the traditional simple limit mechanism. By taking advantage of the fixed-point biting advantage of the cone end, it prevents the wheel body from loosening or shifting during high-speed rotation, ensuring the matching accuracy of the power transmission system.

3. Limiting and calibration of bearings and precision components

Used for the axial limiting and fine-tuning calibration of bearings, bushings, and precision tooling components. The headless hidden structure does not occupy the assembly space and can precisely control the installation gap of the components, achieving micrometer-level assembly alignment, suitable for the assembly requirements of precision automation equipment, instruments, and tooling.

4. Fine-tuning fixation of small mechanical structures

Can be used for the fine-tuning locking of various adjustable frames, positioning blocks, and small motion components. It supports repeated loosening, repositioning, and relocking, suitable for frequent adjustment scenarios such as equipment debugging, micro adjustment of working conditions, and regular precision calibration.

Component Geometry Feature & Custom Fabrication Methodology

DIN 914 cone point grub screws adopt integrated high-precision cold forging and integral hardening treatment process, with strict industrial tolerance control for overall dimensions. The standard internal hex socket is deeply formed with smooth inner wall, perfectly matching precision Allen wrenches, supporting high-torque locking without tool slipping or socket collapse. The precisely polished 90° conical tip features uniform taper and high hardness, capable of stably biting into metal positioning concave points without tip breaking or deformation, realizing zero-slip fixed positioning. The full-section standard metric thread is rolled with dense and neat tooth profile, ensuring smooth screwing, accurate locking stroke and tight thread fit, suitable for frequent adjustment and long-term vibration working conditions. Available in premium stainless steel and high-strength alloy steel grades, the screws deliver excellent hardness, pressure resistance and corrosion resistance, maintaining stable positioning accuracy in various mechanical assembly environments.

5. Diversified material solutions cover multiple application scenarios: 12.9 high-strength steel for heavy-load mechanical positioning, and stainless steel for anti-corrosion and humid environment equipment assembly, widely applicable to machinery, molds, automation and instrumentation industries.

Notes for Attention

1. It is designed to fit the specific positioning holes and prohibits blind pressing and hard locking. The Stainless Steel DIN 914 Cone Point Set Screw achieves positioning by biting into the preset depressions on the pre-defined holes. It is strictly forbidden to forcefully lock on the smooth shaft surface without a positioning hole. This could cause the cone tip to break, the shaft surface to be scratched, the positioning to slip, and fail to achieve the stable anti-torsion effect.

2. It should be installed using standard precision tools: During installation, a matching standard hex socket wrench of the correct size must be used. It is strictly prohibited to use non-standard or worn-out tools to avoid the tool from slipping during locking and the inner hole from being rounded, which could lead to the screw getting stuck, making disassembly difficult.

3. Control the locking force to avoid overload damage: When locking with high torque, force should be applied evenly. Excessive forceful tightening will cause the cone tip to break and the positioning hole to deform, damaging the assembly accuracy and affecting the stability of the equipment's subsequent operation.

4. Differentiate the working conditions and select the appropriate material: For regular indoor machinery, an alloy steel model can be selected to enhance hardness. For damp, outdoor, or corrosive environments, stainless steel material should be used to avoid the lock from failing due to long-term oxidation and rusting and making it difficult to disassemble.

5. Regularly check the locking status in frequent adjustment scenarios: For equipment points that need to be repeatedly adjusted and subject to long-term vibration, regular checks on the locking status are necessary. Loose screws should be promptly tightened to prevent cumulative micro-displacements caused by long-term vibration, which could affect the overall accuracy of the equipment.

6. Do not substitute it for load-bearing locking screws: This product is a precision positioning and limiting accessory. Its core functions are anti-torsion, positioning, and fine adjustment. It cannot be used as a load-bearing, tension, or shear main locking screw. Avoid overloading to prevent breakage and failure.
