- Recommended Products
Cone Point Design for Positive Positioning: The cone point tip provides a defined contact point that engages with the mating surface during tightening. This concentrated contact helps maintain component position under vibration, load changes, or thermal cycling. The cone point is particularly effective when used against shafts, where the point can locate into a pre-drilled dimple or simply bear against the shaft surface to create a positive lock. This feature supports applications requiring precise positioning, such as collars on rotating shafts or adjustment stops on mechanical assemblies.
Stainless Steel Material with Temperature Stability: The 304 stainless steel construction offers corrosion resistance suitable for applications in humid environments, food processing areas, and chemical exposure conditions. The material data indicates that 304 stainless steel maintains its mechanical properties across a temperature range from -196°C to 800°C. This wide operating range supports use in cryogenic equipment, high-temperature processing machinery, and applications involving thermal cycling. The non-magnetic characteristic of 304 stainless steel in the annealed condition can be relevant for equipment sensitive to magnetic fields or where magnetic particle accumulation is a concern.
A2-70 Strength Class for Reliable Fastening: The A2-70 property class designation provides a clear indication of the fastener's mechanical capability. With a minimum tensile strength of 700 MPa, these grub screws offer load-bearing capacity suitable for medium-duty industrial applications. This strength rating supports secure fixing of components without the need for larger-diameter fasteners, enabling compact assembly designs.
Hex Socket Drive for Convenient Installation: The internal hexagon socket drive accepts standard hex keys, supporting straightforward installation using commonly available tools. The recessed socket design allows the screw head to sit flush with or below the surrounding surface, which is useful in applications with clearance constraints or where a low profile is desired. The socket drive also provides good torque transmission without the risk of cam-out associated with some other drive types.
Food and Medical-Grade Equipment: In the food processing industry, grub screws are used to secure components on stainless steel equipment where hygiene standards are important. The cone point design supports positive locking of position indicators, collars, and adjustment mechanisms on machinery surfaces that are subject to regular washdown. The 304 stainless steel material provides the necessary corrosion resistance for food contact environments. Medical apparatus manufacturing specifies these fasteners for equipment where precision positioning is required, such as in diagnostic instruments, surgical table adjustments, and treatment device assemblies where the material's non-magnetic property can be an advantage. Packaging machinery incorporates cone point grub screws for securing timing dials, adjustment knobs, and positioning components, supporting consistent product handling and seal formation.
Industrial Automation and Production Line Components: Within the conveying equipment sector, these grub screws are used to lock collars and position components onto drive shafts and rollers. The cone point engagement helps maintain component position under the vibration and load variations typical of continuous conveyor operation. The machinery for canning sector uses these fasteners for adjustment mechanisms on filling stations and seaming equipment, where precise positioning affects can integrity and production quality. As machine parts, these grub screws serve as essential components for shaft collars, bearing retainers, and adjustment screws across various industrial machinery types, supporting reliable operation through positive mechanical locking.
Heavy Industry and Specialized Environment Equipment: In chemical equipment installations, grub screws must withstand exposure to process fluids, cleaning agents, and varying temperatures. The 304 stainless steel material provides the necessary corrosion resistance, and the material's temperature range supports use in both heated and chilled process equipment. Ship manufacturing uses these fasteners in marine equipment where salt spray corrosion is a concern and where the non-magnetic property can be relevant for navigation and communication equipment. The water treatment industry applies these fasteners in pump assemblies, valve position indicators, and filtration equipment, where moisture exposure is continuous and secure positioning of adjustment mechanisms supports reliable system operation. The cone point design provides positive engagement that helps maintain component alignment in equipment subject to vibration from rotating machinery and flowing media.
The Hex Socket Cone Point Grub Screw is a threaded fastener designed for positioning, fixing, and load-bearing applications where a positive mechanical lock into a mating surface is required. The defining feature of this product is its cone point tip, which provides a concentrated contact point for engaging with the component being secured. When tightened, the cone point creates a localized indentation or positive engagement with the mating surface, helping to maintain the position of the secured component under operational loads. This design is particularly useful for applications where the grub screw is used as a stop, pivot, or locating element against a shaft, collar, or flat surface.
The material specification is 304 stainless steel, an austenitic chromium-nickel alloy that provides a practical balance of mechanical properties and corrosion resistance. According to the material data, 304 stainless steel maintains its mechanical integrity across a temperature range from -196°C to 800°C, supporting use in both cryogenic and high-temperature applications. The material is non-magnetic in the annealed condition, which can be relevant for applications where magnetic interference is a concern. The A2-70 property class designation indicates that this fastener is manufactured from austenitic stainless steel with a minimum tensile strength of 700 MPa. This strength level is suitable for medium-duty fastening applications where load-bearing capacity is a consideration.
The thread configuration is metric coarse thread, the standard thread form for general-purpose metric fasteners. Coarse threads offer advantages in terms of faster assembly and reduced susceptibility to cross-threading during installation. The head style is a flat head with a hexagon socket drive, compatible with standard hex (Allen) keys. The socket drive allows for tool engagement recessed within the fastener head, supporting applications where external access is limited or where a flush-mounted appearance is preferred. The finish is plain, meaning the fastener is supplied in its natural mill condition without additional coatings. For applications requiring enhanced corrosion protection, the material data indicates that options such as anodized or coated finishes may be available. The product is manufactured in China under quality control processes that support dimensional consistency and thread accuracy.
