Fasten44 is an !"cel Spreadsheet Te#plate for finding capacities of $rdinary Bolts, %ountersunk Bolts, &ighStrength Friction 'rip Bolts and Fillet (elds using BS 44: Part ).

The used Tensile Stress *reas are fro#: BS 4+ for $rdinary Black Bolts, BS -) for Precision Bolts andBS 4-- for %ountersunk Bolts. The used Tensile Stress *reas and Proof /oads for &SF' Bolts are fro#: BS44: Part + for 'eneral 'rade and BS 44: Part ) for &igher 'rade 0parallel shank1 bolts.

Fasten44 includes, in built %ell %o##ents, Features and 2ser 3otes. They provide instant infor#ation for aninteractive use of its folloing three orksheets:

. The bolt bearing capacity #bb

is calculated as:

dis the no#inal bolt dia#eter,tis the thickness of the connected ply, or if the bolts are countersunk, the thickness of the ply #inus half thedepth of countersinking, hich is e?ual to half the no#inal dia#eter of bolts, and

pbb

is bearing strength of the bolt obtained fro# %lause 6b and Table ) of BS44.

The tension capacity #tof the bolt is calculated both for the Shank /ength and the Threaded /ength. The

Shank /ength capacity is based on no#inal dia#eter of the bolt and its use is relevant in co#bined Tensionand Bending only, hen shear plane lies in the shank length. The Threaded length capacity is based on tensilestress area of threads and is the critical strength in direct tension and co#bined Tension and Bending henshear plane lies in the threaded length.
