The UnitedBuilt S23762MS packing-gland bolt is a square-head, 3/8-16 x 2-1/2 in. fastener for the M3ZRM rope-packing arrangement. It is used at the packing gland rather than at the volute-case fastening positions.
The pump assembly requires two of these bolts. That is the installation quantity, not a two-bolt package claim. Order the quantity needed for your repair and select any replacement nuts, gland or packing separately.
The square head and 2-1/2 in. length distinguish this bolt from shorter case fasteners. Use the exact S23762MS part number and gland location when matching the existing hardware. A bolt with the same thread size but a different head or length is not automatically the correct substitute.
