9 Major Types of Special Screws: Types and Characteristics of Special Screws
This time, we would like you to know about special screws! Please take a look, and if you have any questions, feel free to consult with us at Equal!
![[Technical Data] Types and Standards of Screws - Inch Screw and Metric Screw Standard Table](https://image.mono.ipros.com/public/product/image/65b/2001516772/IPROS8783806036333061169.jpg?w=280&h=280)
This time, I have summarized the types and standards of screws, so please download it and refer to it when needed.
There are various standards of screws with different thread counts and pitches circulating around us. While mainstream screws are readily available, those that are less common tend to take longer to produce and are more likely to be in short supply. At Equal, we can manufacture screws according to specifications in small lots! Please take a look, and if you have any questions, feel free to consult with Equal! ■Contents - Types and standards of screws About ISO metric screws and inch screws, etc. - ISO metric screw standard table - Inch screw standard table *For more details, please refer to the PDF materials available for download or feel free to contact us.
Ball screw with nut outer diameter dimensions compliant with ISO standards. (Nut outer diameter size reduced!)
- Improved rotational performance and reliability through enhanced strength of circulating parts and optimization of ball trajectories. - Environmentally conscious design that does not use adhesives.
Stainless steel knurled screw, stepped, φ10×H10, degreased.
This is a hand-tightening screw made of SUS303 material. It can be used for securing parts of outdoor devices where corrosion is a concern, and the head itself can be used as a knob. Additionally, since it is a hand-tightening screw, it is suitable for areas that require angle or position adjustments. It is compliant with EU-RoHS standards.
Stainless steel knurled screw, stepped, φ10×H12, degreased.
This is a hand-tightening screw made of SUS303 material. It can be used for securing parts of outdoor devices where corrosion is a concern, and the head itself can be used as a knob. Additionally, since it is a hand-tightening screw, it is suitable for areas that require angle or position adjustments. It is compliant with EU-RoHS standards.
Stainless steel knurled screw with step φ12×H15, degreased.
This is a hand-tightening screw made of SUS303 material. It can be used for securing parts of outdoor equipment where corrosion is a concern, and the head itself can be used as a knob. Additionally, since it is a hand-tightening screw, it is suitable for areas that require angle or position adjustments. It is compliant with EU-RoHS standards.
Brass long screws and full screws
It is a screw without a head, consisting only of the threaded part. Brass has excellent conductivity and is suitable for use in high and low voltage devices and conductive parts. It is also referred to as a long screw, full screw, or cut screw. It is compliant with EU-RoHS standards.
Stainless steel + small pot screw with NBR washer
This is a pan head screw incorporating NBR-made set washers (NBRS series). It prevents the washers from falling off when the screw is removed, thereby reducing the workload during assembly. It is compliant with EU-RoHS standards.
Stainless steel (black dye processing) + small pan screw
This is a representative type of pan screw with a cross recess that is widely used in various fields. It is made of iron and has a high corrosion-resistant black coating (Sabinai-jan). It complies with EU-RoHS2 standards. - High corrosion-resistant black coating (Sabinai-jan) refers to a blackened stainless steel that forms a black film on the surface of the metal, providing high corrosion resistance. In rust resistance durability tests (salt spray), the typical black coating lasts for 72 hours, while the high corrosion-resistant black coating (Sabinai-jan) exceeds 3000 hours. It is suitable for outdoor use and may be used for salt damage prevention in coastal areas and snow removal regions. Applications: Construction, outdoor use, automotive, etc.
If you're worried about overseas procurement, then let's choose a well-managed factory in Japan.
◎ There are local subsidiaries in the following countries! ▶▶ Philippines, Shanghai, Hong Kong, Vietnam (in order of establishment) ◎ The local subsidiaries serve as points of contact, allowing direct communication with the factories! ▶▶ They are within a distance that allows for factory visits, providing peace of mind. ◎ Many local factories are either Japanese-owned or well-managed by Japanese standards! ▶▶ This alleviates concerns about quality and delivery times. ◎ Semi-local procurement is also possible! ▶▶ By supplying goods exported from Japan through the local subsidiaries, it contributes to increasing the local procurement rate.
It is possible to specify the application range, color, and viscosity of the locking agent! Since the locking agent is already applied to the threaded part, tightening can be done directly.
The screw with anti-loosening processing, "Seahorse Lock(R)," is a pre-coated type with an anti-loosening agent applied to the screw part, allowing for tightening work to be done immediately as an adhesive-based anti-loosening product. It eliminates the hassle, inconsistency, and forgetfulness of the application process, and strongly prevents loosening due to impact and vibration. The anti-loosening agents can be broadly categorized into two types: "resistance" and "adhesion," with multiple varieties available for each type, allowing for differentiation based on application needs. This product contributes to reducing the labor involved in the application process and streamlining operations. 【Features】 ■ Eliminates the hassle, inconsistency, and forgetfulness of adhesive application work ■ Customizable types, application ranges, viscosities, and colors of anti-loosening agents ■ Supports prototyping, small lots, and short delivery times ■ Specialized engineers are available to assist with specification selection and setting various torque values using testing equipment *For more details, please download the PDF or contact us directly.
It can reduce noise compared to ball screws! Low-friction resin nut sliding screw!
The "P-MSS Series" is a low-friction, low-noise resin nut type lead screw! With a low-friction resin nut, it achieves smooth movement and low noise at a lower price than ball screws! The screw shaft is made of stainless steel, providing a certain level of strength and making it usable in a wide range of environments. 【Features】 〇 Affordable pricing 〇 Capable of producing small lots and a variety of products with short delivery times 〇 Stainless steel screw shaft with excellent corrosion resistance, usable in a wide range of environments 【Examples of Applications】 〇 Medical devices 〇 Semiconductor manufacturing equipment 〇 Food machinery 〇 Automotive production equipment ... and others, such as LCD production equipment.
"We would like to request surface treatment... We would like to request processing of the shaft end shape..." We are providing materials that explain common issues and solutions encountered when purchasing ball screws.

Aluminum sash construction drill screws that prevent chip entrapment and pinching.
When using a standard drill screw on aluminum, the chips become long, which can lead to them getting caught during construction and can cause unexpected injuries. Al-Drive is a drill screw with a special cutting edge that cuts and breaks up the chips to prevent them from getting caught. It is targeted for aluminum sash construction and is available in four colors—silver, gold, bronze, and black—to match the color of the sash. Of course, it can also be used on steel materials other than aluminum sashes.
One-sided fastening, no welding required, Ministry of Land, Infrastructure, Transport and Tourism certification, construction structural drill screws.
Large drill screws with an outer diameter of φ8mm. Can be fastened to steel materials with a thickness of up to 13mm without pre-drilling. This is a series of structural drill screws that can be used with structural steel such as H-beams.
