Hex Cross Recess Combination Machine Screw

Adopting precision standard machine thread and one-piece cold heading forming technology, the screw features accurate tooth pitch, smooth locking and excellent anti-vibration performance. It perfectly balances convenient manual assembly and high-torque mechanical fastening, widely used for electrical equipment, cabinet hardware, mechanical accessories, furniture connection and general industrial assembly scenarios.

Compound Cold Heading Forming & High-Precision Thread Rolling Craft

This hex cross recess combination screw is manufactured via fully automatic cold heading integral forming process, with compact internal metal structure, stable hardness and strong toughness. The special hex head with inner cross recess is precisely stamped and formed with smooth surface and standard groove size, ensuring perfect fit with both cross screwdrivers and hex socket tools without slipping or tool damage. The thread is processed by secondary precision rolling, featuring full tooth profile, uniform pitch and accurate tolerance for smooth meshing and tight locking. Pre-assembled flat washers and spring washers are fixed by high-pressure crimping technology, effectively avoiding gasket falling off, displacement and loss during transportation and installation. Multiple surface anti-rust treatments including electro galvanizing, color zinc plating and black passivation endow the screw with excellent corrosion resistance, adapting to long-term indoor and light industrial working environments.

Multi-Tool Adaptability & General Industrial Fastening Merits

1. Unique dual-drive structural design. Combining external hexagon and internal cross recess functions, the screw supports both manual screwdriver fastening and electric socket high-torque locking. It solves the tool limitation of single-drive screws, greatly improving on-site construction flexibility and assembly efficiency.

2. Dual anti-loosening protection system. Equipped with matched flat and spring composite gaskets, the combination structure disperses fastening pressure evenly and provides continuous elastic pre-tightening force. It effectively resists equipment operation vibration and external pressure changes, preventing thread loosening and ensuring long-term stable connection.

3. Factory integrated assembly saves costs. Pre-assembled three-in-one structure eliminates manual gasket matching and sorting, avoiding common problems such as gasket loss, mismatching and missing installation in batch production. It optimizes assembly line processes and reduces labor operating costs.

4. High-precision thread & strong versatility. Adopting industrial standard machine thread rolling process, the thread size is accurate and meshes smoothly with all standard threaded holes and hardware accessories. It features high fitting accuracy, no sliding teeth or jamming, suitable for diversified general industrial fastening scenarios.

5. Stable quality & wide application coverage. With mature cold heading production and anti-corrosion treatment technology, the screw has stable mechanical properties and durable surface protection. It is the preferred universal fastener for electrical, furniture, machinery and civilian industrial fields, with high cost performance and reliable batch supply capacity.

FAQ
