The core installation logic of the tamper-resistant screw (also known as a spring screw or panel screw) is: first, rivet the base → then hand-tighten the pre-positioning → finally tighten with a tool. After installation, the screw will not fall out of the panel when loosened, suitable for sheet metal, chassis, PCB board, and other scenarios.
Socket head screw plugs provide reliable sealing for hydraulic, automotive and machinery systems — withstanding high pressure while allowing easy access for maintenance and fluid changes.
In the precision system of industrial manufacturing, insert nuts, as key components for connecting plastics and metals, play an irreplaceable role in various industrial scenarios by virtue of their diverse installation methods and significant advantages. These small parts with knurling on the outside and internal threads, through scientific design and precise installation, endow products with stab
The alloy trumpet-head self-tapping nut cuts its own thread in wood, plastic and soft alloys, with a flared head that spreads load. A smart fastening solution for machinery, electronics and furniture.
Nickel plating upgrades socket head (pan head) screws with superior corrosion resistance, wear resistance and a clean appearance — ideal for electronics, precision instruments and outdoor equipment.
The six-claw grounding washer (grounding disc-spring lock washer) delivers reliable electrical grounding and anti-loosening in rail, electrical, elevator and machinery applications.
Beside construction scaffolding, in auto repair workshops, or on the walls of home renovations, you can often see an ordinary-looking yet highly functional metal component—wedge anchors (known as "车修壁虎" in Chinese). This somewhat special-sounding name is not only linked to its application in the auto repair field but also implies its gecko-like ability to firmly "grip" objects. As a widely used ex
On June 24th, a personal casualty accident occurred to an outsourced worker during wind turbine installation operations at the 3rd Construction Section of a wind power project in Hami, Xinjiang. One person was killed.
Preliminary assessment indicates that the base bolts of the turning tooling torque arm fractured, causing the torque arm to fail and disengage, which then struck the worker Mr. Wen
Due to issues such as loose bolts, these cars have been recalled nationwide
The Inevitable Development Trend of the Plastic Screw Industry
Denso Wave of Japan Launches High Precision Screw Locking Robotic arm
The epidemic affects the supply of parts: or hits the production of Japanese automakers
Since the screw was invented in 1550, preventing loosening has been a constant challenge. Learn the three mature anti-loosening methods: friction, mechanical and permanent locking.
Resin screws are made to JIS and ISO standards but differ from metal screws in production. Learn material selection (RENY, PPS, PEEK, VESPEL), torque handling and chemical-resistance notes.
Miniature screws for toys, models and earphones require high strength, small size, eco-friendly plating and easy installation. Jiali supplies custom miniature screw solutions with samples in stock.
The eyebolt is forged by warm quenching. Surface treatment of eyebolt: corrod-dt, which is at least 20 times more effective than ordinary zinc plating. Length of external thread ¨ H ¨， The bolts are fixed with other parts, and the bolts of the same quality grade must be selected for replacement.
Square mother, hardware equipment, fastening accessories. It is square in shape with internal thread and can be used with bolt. It is also called square nut.
Nut is a part that connects mechanical equipment closely, also called root nut, lock nut or receiver. The main purpose is to lock the external joint or other pipe fittings of the thread.
Hexagon socket set screw, hexagon flat set screw, hexagon cylindrical set screw.
As we all know, nuts and bolts are small parts that play the role of fastening and connecting when fixing tools, with the characteristics of easy installation, integrity, no washer, easy disassembly and so on. Generally used as nut materials are carbon steel, stainless steel, copper, alloy, etc. Among many kinds of nuts, butterfly nut is very convenient to use because of its unique shape - the but
