DIN 7643 Banjo Bolts for Hydraulic, Fuel and Lubrication Lines
High-Performance DIN 7643 Banjo Bolts by Handan Haosheng Fastener Co., Ltd.
In hydraulic, fuel, and lubrication systems where installation space is limited and reliable fluid transfer is critical, banjo bolts have become the preferred connection solution. Handan Haosheng Fastener Co., Ltd., a leading manufacturer based in Handan, China, specializes in producing high-quality DIN 7643 banjo bolts (hollow screws), offering integrated fastening and fluid transfer in one compact component.
Manufactured from Q235 carbon steel to DIN 7643 dimensions, our banjo bolts combine an axial bore with radial holes to deliver compact, washer-sealed connections for demanding fluid systems.
Why Choose DIN 7643 Banjo Bolts?
Banjo bolt connections provide several key advantages:
✔ Integrated Fastening and Fluid Transfer – The axial bore and radial holes create an internal flow path while the bolt secures the banjo fitting, combining two functions in one component.
✔ Compact Connection Design – The fitting rotates around the bolt body, enabling tight pipe routing where elbow fittings cannot fit.
✔ Multiple Hole Configurations – Choose from 1, 2, 3, 4, or 6 radial holes, with hole diameter and position confirmed according to your drawing.
✔ Reliable Washer Sealing – Sealing washers on both sides of the fitting keep potential leak points to a minimum.
