Is the Lock nut BSP thread, carbon steel, type A108 compatible with adapter type A107 after galvanizing?

Yes . Lock nut BSP thread, carbon steel, type A108 is compatible with adapter type A107 after galvanizing. The product description explicitly states it is "for use with adapter type A107" and both parts are intended to work together. Galvanizing the carbon steel lock nut provides a protective zinc coating that does not change the BSP thread form or dimensions, so the threaded fit and mechanical compatibility with A107 remain intact. Ensure both components use the same BSP thread series (e.g., BSPP or BSPT) and matching nominal size; if A107 is also galvanized or finished differently, verify any assembly torque or sealing requirements per manufacturer guidance to avoid galling or impaired sealing.

Can the Lock nut BSP thread, carbon steel, type A108 withstand corrosion after galvanizing when used with adapter type A107?

Yes. Lock nut BSP thread, carbon steel, type A108, galvanized, can withstand corrosion when used with adapter type A107 provided both parts receive compatible surface protection and are installed in appropriate environments. Galvanizing (zinc coating) offers good corrosion resistance for carbon steel in many atmospheres; when both the Lock nut BSP thread, carbon steel, type A108 and adapter type A107 are galvanized or otherwise corrosion-protected, galvanic compatibility is preserved and corrosion risk is low. However, longevity depends on exposure conditions (marine, chemical, or high-humidity environments reduce service life), coating quality/thickness, and correct assembly (no damage to coating, avoiding dissimilar metals contact). For critical or harsh environments, consider additional protective measures (thicker hot-dip galvanizing, epoxy coating, or stainless steel components).

Does Lock nut BSP thread, carbon steel, type A108 require re-torquing after installation with adapter type A107?

No. Lock nut BSP thread, carbon steel, type A108 does not normally require re-torquing after installation with adapter type A107 if installed correctly the first time. The lock nut is designed to provide a secure, vibration-resistant connection when tightened to the specified torque and assembled with the matching A107 adapter. Re-torquing is generally unnecessary unless one of the following occurs: - The initial installation torque was not applied correctly or to the manufacturerâs specified value. - Components show signs of loosening, damage, corrosion, or wear during inspection. - Assembly conditions (e.g., thread lubrication, plating, or surface condition) differed from those assumed in the installation torque spec. - A critical application or safety procedure or company policy mandates a verification or re-torque after initial service. If manufacturer instructions or project specifications for Lock nut BSP thread, carbon steel, type A108 and adapter type A107 explicitly require re-torquing, follow those. Otherwise, perform routine inspections and only re-torque when evidence of loosening or maintenance procedures call for it.
