DIN913 Hexagon Socket Set Screw Flat Point

In modern precision machinery, automated equipment and industrial tooling assembly, traditional headed screws often cause structural interference due to protruding heads, which affects equipment operation accuracy and assembly compactness. Therefore, headless set screws have become essential standard fasteners for high-precision assembly scenarios. DIN913 Hexagon Socket Set Screw Flat Point is a widely adopted German standard grub screw with full thread structure and flat end contact design. Different from cone point and cup point set screws, its flat end provides uniform stress distribution without scratching, denting or damaging the surface of shafts, aluminum parts, copper accessories and precision tooling components. All products of Gangtong Zheli are strictly manufactured in accordance with DIN standard dimensions, thread tolerance and mechanical performance requirements. We supply complete size ranges, diverse material grades and multiple surface treatments to meet indoor, outdoor, dry, humid and lightly corrosive working environments. Both standard stock orders and customized non-standard specifications are supported to satisfy different mechanical assembly and engineering procurement demands.

Material Grade & Surface Treatment Introduction

Different usage scenarios require matched material hardness, tensile strength and anti-rust performance. To help customers achieve accurate selection and avoid installation failure or short service life caused by improper material selection, Gangtong Zheli provides two mainstream material grades and multiple surface finishing solutions for DIN913 Hexagon Socket Set Screw Flat Point. Each processing technology is strictly controlled to ensure stable hardness, precise thread and excellent surface protection effect.

Structural Advantage & Product Type Comparison

DIN standard set screws are divided into four mainstream types according to end shape: flat point, cone point, cup point and dog point. Each structure has completely different mechanical characteristics and applicable working conditions. Many engineers confuse these types and easily cause insufficient locking or shaft damage. The flat-end structure of DIN913 Hexagon Socket Set Screw Flat Point focuses on precise positioning and protective locking, which is irreplaceable in precision equipment assembly.

Wide Application Scenarios of DIN913 Set Screw

With headless embedded design, flat protective end and high-precision full thread, DIN913 Hexagon Socket Set Screw Flat Point is widely used in almost all precision mechanical assembly fields that require hidden installation, adjustable positioning and non-damage locking. Its biggest feature is that it can be completely embedded into the threaded hole without protruding, ensuring neat and compact equipment structure and avoiding interference with moving parts.

Precision Machine Tools & Automation Equipment

Used for fixing gears, bearings, spacing sleeves and limit rings on precision shafts. It can precisely adjust the axial position of parts, effectively solve the displacement problem of mechanical accessories during long-term vibration operation, and will not scratch the polished shaft surface.

Motor, Pump Body & Reducer Assembly

Suitable for positioning motor shaft couplings, pump body internal limit parts and reducer transmission components. The flat end uniformly bears mechanical pressure to prevent local stress concentration and extend the service life of mechanical transmission parts.

Instrument, Optics & Testing Tooling

High-precision equipment such as optical brackets, detection jigs and sensor fixing structures have extremely high requirements for surface protection. Stainless steel DIN913 set screws can achieve rust-free long-term positioning without damaging precision accessories.

Mold Standard Parts & Tooling Fixtures

Commonly used for mold insert positioning, limit locking and fixture adjustment. It supports repeated disassembly and debugging, which greatly improves the flexibility of mold and tooling trial production.

Automotive & Mechanical Auxiliary Components

Applied to hidden limit assembly of automobile transmission parts, chassis auxiliary accessories and vehicle electrical modules, adapting to long-term vibration working conditions.

Packaging, Inspection & Shipment Standard

For industrial standard fastener bulk orders, stable packaging quality and complete pre-shipment inspection are the key factors to ensure zero defective delivery. Gangtong Zheli implements standardized export packaging process for all DIN913 Hexagon Socket Set Screw Flat Point products. The inner layer adopts moisture-proof and rust-proof plastic bags to prevent oxidation and rust during long-distance sea transportation. The outer layer uses thickened drop-resistant export cartons. Large batch orders will be neatly stacked and fixed on solid wooden pallets to avoid extrusion, collision and thread damage during transportation.

Each carton is labeled with clear information including product standard, size specification, material grade, surface treatment, gross weight, net weight and production batch number, facilitating customer warehouse management, inventory checking and customs clearance. We support customized private labels and special packaging requirements. Before shipment, all products will pass dimensional inspection, thread tolerance detection and appearance screening to ensure consistent batch quality.

For large-scale engineering bulk orders, we arrange production reasonably to ensure on-time delivery. Meanwhile, we support non-standard customization of special lengths and special sizes according to customer drawings and samples, providing one-stop fastener matching solutions. We provide professional pre-sales technical selection guidance and after-sales tracking service, winning stable cooperation with global hardware distributors and mechanical equipment manufacturers.

FAQ

Q1: What is the essential difference between DIN913 and DIN916 set screws?

A1: DIN913 adopts flat end design, which is suitable for precision positioning and adjustable assembly without damaging the shaft surface. DIN916 is cup point type with strong clamping force, easy to form indentation on the contact surface, more suitable for fixed locking without repeated adjustment.

Q2: Can DIN913 flat point set screws be used for high-strength heavy load locking?

A2: This product is mainly used for positioning, limiting and anti-loosening of auxiliary parts, not recommended for main bearing heavy-load connection. For heavy-load structural locking, please choose high-strength bolts or professional load-bearing fasteners.

Q3: Do you support custom non-standard sizes?

A3: Yes. We support customized special lengths, special thread pitches and special surface treatments. You can provide drawings or size parameters for professional evaluation and quotation.

Q4: What kinds of surface treatments can you provide?

A4: We provide black oxide, blue white zinc, yellow zinc, passivation and other treatments to adapt to indoor dry, humid environment and outdoor anti-rust requirements.

Q5: Can you provide samples for testing?

A5: Yes, free samples are available for quality and size verification before bulk purchasing.
