Asɛmmisa: Nsonsonoe titiriw bɛn na ɛwɔ metric thread ne BSP thread ntam?
A: Nsonsonoe titiriw a ɛda metric thread ne BSP thread ntam no da wɔn nhyehyɛe ne susudua nhyehyɛe mu. Metric threads di metric susudua nhyehyɛe akyi, de milimita di dwuma ma nhama no nnyigyei ne ne ntwemu.

Asɛmmisa: So wobetumi de metric thread adi dwuma de asesa ne BSP thread?
A: Metric threads ne BSP threads no ntumi nsesa esiane wɔn susudua ahorow ne nhyehyɛe ahorow nti. Metric threads wɔ pitch a ɛyɛ fɛ na ɛsono thread angle a wɔde toto BSP threads ho. Sɛ wobɔ mmɔden sɛ wobɛsesa wɔn a, ebetumi ama woayɛ nea ɛfata, ɛbɛtwe, anaasɛ ɛbɛsɛe nneɛma a ɛwɔ asaawa no mu.
Q: So standardization ahyehyɛde ahorow bi wɔ hɔ ma metric thread ne BSP thread?
A: Yiw, standardization ahyehyɛde ahorow wɔ hɔ ma metric thread ne BSP thread nyinaa. Amanaman Ntam Ahyehyɛdeɛ a ɛhwɛ gyinapɛn so (ISO) no de gyinapɛn a ɛfa metric threads ho si hɔ, na ɛhwɛ ma ɛne aman ahodoɔ hyia wɔ aman ahodoɔ so.

A: Wɔde metric nhama di dwuma kɛse wɔ nnwuma te sɛ kar, mfiri, ne nneɛma a wɔyɛ mu. Wɔtaa hu wɔn wɔ Europa ne Asia aman a metric nhyehyɛe no yɛ gyinapɛn susudua nhyehyɛe no mu. Metric threads ma nkitahodi a ɛyɛ pɛpɛɛpɛ na wotumi de ho to so, na ɛma ɛfata ma application ahorow.
Asɛmmisa: So mfaso bi wɔ so sɛ wode BSP thread bedi dwuma wɔ metric thread so?
A: BSP nhama no wɔ mfasoɔ wɔ dwumadie bi mu. Wɔtaa de di dwuma wɔ nsu ho nhama ne nsu ho nhyehyɛe mu, titiriw wɔ aman a wodi Britaniafo susuw nhyehyɛe no akyi no mu. BSP nhama no wɔ taper design, a ɛma kwan ma nsɔano a ɛyɛ den ne resistance a eye ma leakage sɛ wɔde toto metric threads ho a.
