Essential Knowledge About Screws!
This time, we would like to share some basic knowledge about screws that we hope everyone will find useful! Please take a look, and if you have any questions, feel free to consult with us at Equal.
Directly connected motor feed screw
【Features】 ■Direct Connection Structure - Directly connects a 2-phase stepping motor with KSS-made resin lead screw (shaft diameter: φ8.10, lead: 2, 5, 10, 20). - Achieves an ideal structure where the screw axis aligns with the motor rotation axis. ■Oil-Free Specification - Standardized with MRH nuts made of polyamide, which have excellent sliding characteristics. - Enables use without lubrication. ■Reduction of Work Steps - No need for alignment between the motor and screw due to the direct connection structure. ■Low Cost - Achieves a versatile and low-cost product through the combination of resin lead screw and 2-phase stepping motor. ■Quiet Operation - By adopting a resin lead screw, it achieves quiet operation during sliding. - The shaft is made of SUS304, providing excellent corrosion resistance.
The new comprehensive catalog is being distributed by a manufacturer specializing in miniature ball screws.
The SG series has products in stock with shaft diameters ranging from φ3mm to φ15mm. The SD series underwent a significant lineup review in 2010, and we have products in stock with shaft diameters ranging from φ4mm to φ12mm.
Ultra-small X ultra-precision
KSS precision ball screws are available as standard stock items that can be produced in a short lead time, as well as custom-made products where the shaft end shape can be freely designed. To meet our customers' demands for short lead times, KSS maintains standard stock for specific model numbers. The shaft end shapes are standardized, allowing for a reduction in design man-hours for our customers. In addition to standard stock items, KSS also offers custom-made products to accommodate all customer designs. To reduce our customers' design man-hours, we have standardized various nut types.
We also accept the production of various special specifications to meet our customers' requests, utilizing the skills we have cultivated up to now.
We also manufacture ball screws using various materials for special environments that conventional steel materials cannot handle. For rust prevention, we can produce ball screws with black chrome treatment (compliant with RoHS) applied to the screw shaft and nut. We also manufacture other special shapes.
Attention users of Y-shaped recess and three-leaf recess screws! This is a screw that improves work efficiency.
The high-performance screw with a wide fan shape featuring three blades, known for its excellent stability, offers superior fit and prevents cam-out, resulting in high-precision fastening. The screw recess is designed with a sloped guide that quickly directs the bit to the center of the screw, providing excellent workability. It also demonstrates tremendous effectiveness in automation, which has traditionally been considered difficult.
Newly designed hexarubular hole
The Intatork, which pursues functionality and workability, features a conical inclined guide at the tip of the bit, automatically guiding the bit to the center of the screw. Furthermore, the locking part at the tip fits securely all the way in. With an excellent design for straightness, it allows for stable fastening without wobbling during the tightening process. Even beginners can perform speedy and reliable work. There is no worry about stripping the head, significantly improving the quality of screw fastening.
Iron + small screw for pot, trivalent chromate black color
It is a representative shape of screws that are widely used in various fields. It is compliant with EU-RoHS standards.
Steel + small screw with nylon washer, black trivalent chromate.
This is a pan head screw incorporating a nylon 66 set washer (NNS series). It prevents the washer from falling off when the screw is removed, thereby reducing the workload during assembly. The washer has excellent abrasion resistance, oil resistance, and gas barrier properties. It is compliant with EU-RoHS standards.
Iron + small screw with spring washer and nylon washer, trivalent chromate black color.
This is a pan head screw with a spring washer incorporating a nylon 66 set washer (NNS series). It prevents the washer from falling off when the screw is removed, thereby reducing the workload during assembly. The washer has excellent abrasion resistance, oil resistance, and gas barrier properties. It is compliant with EU-RoHS standards.
Iron + truss small screw trivalent chromate black color
The head shape resembles the upper part of a sphere. Due to its larger outer diameter compared to other heads, it allows for a wider contact area on the seat surface. It is compliant with EU-RoHS standards.
Steel cup screw with flange, trivalent chromate black.
This is a screw that adds two functions to a pan head screw: a flat washer (large seating surface) and a spring washer (for preventing loosening). It enhances vibration resistance and increases the anti-loosening effect. The cup screw is a registered trademark of Nitto Seiko Co., Ltd. It is compliant with EU-RoHS standards.
Iron + low head screw (laminate) trivalent chromate black color
Supports the realization of thin and lightweight ultra-thin head-shaped screw products. Head height is 35% compared to JIS pan head. Laminate is a trademark of Nitto Seiko. Compliant with EU-RoHS standards.
Iron precision machinery use No. 0 type 2 + small pan screw trivalent chromate black.
Specifications: This product is designed with a lower screw head than the cross-hole pan screws of the Japan Camera Industry Association standard (JCIS10-70) JIS standard. It is also referred to as size 0 screws, micro screws, or camera screws. It is compliant with EU-RoHS regulations.
Iron precision equipment type 0, type 1 + B-tight screw, trivalent chromate black.
Specifications: This product conforms to the Japan Camera Industry Association standard (JCIS10-70) and features a smaller screw head compared to JIS standard cross-recessed pan head screws. It can be tightened while forming a female thread in the counterpart material, eliminating the need for female thread processing or nuts. The cross-section of the screw is shaped like a rice ball (triangular), allowing for fastening with a smaller torque compared to tapping screws. It can be used with both metal plates and plastic components. It enables standardization and integration of screws during assembly manufacturing. It is compliant with EU-RoHS regulations.
