Screws

Screws

As a source factory, our self-tapping screws, machine screws, and wood screws are made of high-quality carbon steel or stainless steel, with sharp thread forming and strong locking force. We support customization of head types, drive styles, and threads, and offer eco-friendly surface treatments such as blue-white zinc and Dacromet for excellent corrosion resistance. Suitable for applications from precision electronics to heavy machinery, ensuring no slipping during fastening.

Anchors

Anchors

Our anchor series includes nylon sleeves, metal sleeve anchors, and chemical anchors. Made of virgin materials, the sleeves offer high toughness and aging resistance. The precise fit between taper and thread ensures even expansion and strong holding power. Suitable for solid bricks, concrete, and hollow brick walls, providing high safety factors for loads and reliable support for curtain walls and guardrails.

Bolts

Bolts

From hex head and carriage bolts to high-strength hex bolts, we use cold heading technology with precise shank reduction and fatigue-resistant thread root radii. Strictly following GB, DIN, and ISO standards, our bolts range from grade 4.8 to 12.9, and we offer customization with Dacromet or hot-dip galvanizing to ensure anti-loosening and shock resistance in mechanical assembly and steel structures.

Nuts

Nuts

Our range of hex nuts, flange nuts, and cap nuts feature precise dimensions and 100% thread gauge inspection. Made of high-quality wire rod, they maintain a balance of hardness and toughness after heat treatment, preventing slipping or chipping during tightening. Options include nylon inserts or all-metal locking types for high-vibration applications.

Rivets

Rivets

Blind rivets and rivet nuts are made of high-quality aluminum, stainless steel, or carbon steel. The mandrels are heat-treated for high tensile strength, with smooth breakage and full expansion for a tight joint. Resistant to vibration and loosening. Customizable with colored aluminum caps or large flange specifications, widely used in sheet metal, vehicles, and ventilation ducts.

Washers

Washers

Flat washers, spring washers, and square taper washers are precision-stamped or machined with high concentricity and deburred to prevent surface damage. Spring washers offer stable elasticity after heat treatment for effective anti-loosening; flat washers have uniform plating for long salt spray resistance. We offer customization of non-standard thicknesses and materials to ensure even preload distribution.

RIGGING

Wire Rope Clips

Our wire rope clips are precision‑crafted from high‑grade stainless steel with smooth polished surfaces for superior corrosion resistance and rustproof performance. The U‑shaped shackle and stable saddle structure deliver firm clamping force to secure wire ropes tightly without slipping or loosening. Standard‑sized bolts and nuts ensure quick assembly and reliable load‑bearing capacity, ideal for rigging, lifting, marine engineering, and general construction applications.
