Fill-in-the-blank: Based on their structural design, bolts can be divided into ( ) bolts and ( ) bolts; double-headed bolts, on the other hand, are classified into ( ) and ( ). Single-ended, Double-ended, Threaded, Unthreaded
Depending on their structural design, bolts can be divided into (single-headed) bolts and (double-headed) bolts. Double-headed bolts, in turn, are further classified into (through-threaded) and (non-through-threaded) types.
Single-end, Double-end, Two-ended thread (Type A), Full thread (Type B)
Bolts are classified by structure into (single-headed bolts) and (double-headed bolts); double-headed bolts are further divided into (fully threaded) and (non-fully threaded)
Depending on their structural design, bolts can be divided into (single-ended) bolts and (double-ended) bolts. Double-ended bolts, in turn, are categorized into (fully threaded) and (double-threaded) types.
Depending on their structural design, bolts can be divided into two categories: (single-headed bolts) and (double-headed bolts). Double-headed bolts, in turn, are further classified into (threaded) and (unthreaded) types.
Single-end and double-end, semi-threaded and fully threaded
Depending on their structural design, bolts can be divided into two categories: (hex head) bolts and (double head) bolts. Double head bolts, in turn, are further divided into two types: (through-threaded) and (non-through-threaded).
