• bolt

This is a screw with a head that has the same shape as the threaded part and features a hexagonal hole. It is tightened using a hexagonal rod wrench (hex key). It is used to press the tip of the screw against the mating part to secure it. The pointed tip of the screw is embedded into the mating part for fixation. It is also known as a set screw or grub screw. It is compliant with EU-RoHS2 standards.

• bolt

This is a low-head hexagonal socket screw with a fluorescent lemon color applied to the head. The highly visible neon color is intended for use in disaster prevention, alerting attention, and highlighting areas that need to stand out. It fits neatly and smartly even in tight spaces, making it ideal for portable and slim devices. The smooth finish prevents snagging and skin injuries, enhancing safety. Its inconspicuous screw head is popular for products that prioritize design. Since counterboring is not required, it is recommended when you want to reduce processing costs. It is compliant with EU-RoHS2 standards.

Specification: Japan Camera Industry Association Standard (JCIS10-70) This is a precision instrument 0-size type 1 + pan head screw with a Nylock treatment on the threaded part. The screw head is smaller than that of a JIS standard pan head screw with a cross hole. The 0-size type 1 + pan head screw is also referred to as a micro screw or camera screw. It complies with EU-RoHS2 standards. - About the anti-loosening treatment Nylock is a reliable anti-loosening processing technology that permanently adheres special nylon to the threaded part. The principle of Nylock's anti-loosening is that when the screw is tightened, the elastic rebound force of the adhered special nylon generates a strong frictional bonding force across the entire threaded part on the opposite side of the processed area, providing a permanent anti-loosening function against vibrations and shocks. It exhibits excellent anti-loosening effectiveness in frequently used areas. This offers advantages not found in bonded anti-loosening products or lock nuts that deform the threaded part. Nylock is a registered trademark of Nylok LLC. *Please inquire separately as specifications may change when used in critical safety locations such as railway vehicles, aircraft, and military applications.

Resin-Specific Anti-Loosening Self-Tapping Screw "Giza Tight" The screw features square grooves divided into four sections around its circumference, providing a strong anti-loosening effect in harsh environments such as vibrations and temperature changes. The asymmetrical screw threads alleviate fatigue in the female threads, allowing for smooth insertion. The sharp threads easily bite into the female threads, preventing boss breakage, and they deeply embed into the resin, enhancing the anti-backout effect. The groove depth is approximately 70% of the thread height, and the escape groove angle is less than 90°, allowing for repeated use. Giza Tight is a registered trademark of Nitto Seiko Co., Ltd. It complies with EU-RoHS2 standards.

This is a hex socket bolt (cap bolt) treated with a low-temperature black chrome process that features a thin film with high corrosion resistance and a matte black color. The non-glossy black surface is ideal for optical devices that require anti-glare properties. It has corrosion resistance that is several tens of times greater than black dyeing. The low-temperature black chrome treatment offers excellent wear resistance, light-selective absorption, and thermal absorption, leading to increased demand in industries related to semiconductors, LCDs, and optical technologies. It is tightened using a hexagonal rod wrench (hex key), making it suitable for tightening in narrow spaces where using a spanner or wrench is difficult. It complies with EU-RoHS2 standards. Applications: Semiconductor and LCD manufacturing equipment, optical inspection equipment, top covers and diaphragm parts of high-end single-lens reflex digital cameras, precision drive components such as LM guides and gears, etc. Standard film thickness: 3 to 12 μm. Since there is no need to apply oil, it can be used in clean rooms.
