This booklet clearly explains the benefits of the special screw tap series "TRI for Tripods" in an easy-to-understand manga format. These are screws with a special standard for camera tripod mounting. A dedicated tap for tripod mounting screws is required for processing the internal threads. To ensure compatibility, JIS has established standards for creating oversized internal threads. Additionally, our company offers custom solutions such as roll taps for mass production processing. 【Product Lineup】 ■ Hand Tap for Tripods "HT TRI" ■ Spiral Tap for Tripods "SP TRI" *For more details, please refer to the link below or feel free to contact us.

This booklet provides an easy-to-understand explanation of the benefits of the simple inspection tool series, Tap Hole Check Pins 'CPC-S, CPC-T, CPR-S, CPR-T' through manga. For "reliable screws," managing the pilot hole is crucial. You can easily and accurately check the dimensions of the tap hole diameter. We offer a straight type that allows for precise inspection of the pilot hole diameter and a tapered type that can only inspect the entrance of the pilot hole diameter. 【Check Pin Features】 ■ Easy and accurate pilot hole diameter checking ■ Reduction of processing troubles ■ Increased lifespan of taps ■ Overall cost reduction *For more details, please refer to the link below or feel free to contact us.

This brochure explains the benefits of the short chamfer hand tap 'MG-HT' for magnesium alloy castings in an easy-to-understand manga format. The number of threads in the engaged portion is less than one, allowing processing up to the limit of the hole depth. The blade design that reduces heat generation during processing results in a clean internal thread surface and eliminates inner diameter burrs. Additionally, it features a groove shape suitable for zinc alloy castings and aluminum alloy castings. 【Features】 ■ The number of threads in the engaged portion is less than one ■ Processing is possible up to the limit of the hole depth ■ Blade design that reduces heat generation during processing ■ Clean internal thread surface and elimination of inner diameter burrs ■ Groove shape suitable for zinc alloy castings and aluminum alloy castings *For more details, please refer to the link below or feel free to contact us.

This booklet explains the benefits of the simple inspection tool series "SIT/SITD" in an easy-to-understand manga format. "SIT" is a tool that can determine the quality of internal threads with the same precision as a screw gauge. The tip of the screw section is designed as a step screw, making it easy to engage with internal threads, even with fine thread pitches. 【Features of SIT】 ■ Can determine the quality of internal threads with the same precision as a screw gauge ■ Easy to use even with fine thread pitches ■ Made with high-speed steel for long lifespan ■ Cheaper than screw gauges *For more details, please refer to the link below or feel free to contact us.

This booklet clearly explains the advantages of the hand tap series for left screws, 'HT LH', using manga. Fans use "left screws," and when counterclockwise force is applied to the cap, there is a risk that the blades may fall off if right screws are used, as they would loosen in that direction. Therefore, left screws are employed. Additionally, our left screw taps are available not only in standard types "HT LH," "SP LH," and "PO LH," but also through custom manufacturing. 【Features】 ■ There are three standard types in the left screw tap series: Hand tap for left screws "HT LH" Spiral tap for left screws "SP LH" Point tap for left screws "PO LH" ■ Left screws tighten counterclockwise ■ When the motor shaft rotates clockwise, counterclockwise force is applied to the cap ■ When counterclockwise force is applied to the cap, there is a risk that the blades may fall off if right screws are used, which is why left screws are utilized. *For more details, please refer to the link below or feel free to contact us.
