Mary ANN Sinde, doing business as Mas Mechanical Solutions, is a woman-owned small business sole proprietorship based in Mobile, Alabama, that supplies precision mechanical components and specialized tools to the Department of Defense as a prime contractor, competing full-and-open without set-asides across 86 recent federal awards totaling $5 million in combined potential value.

Mas Mechanical Solutions manufactures and delivers input module seals, taper pin tools, and MGB tie rod tools for military equipment maintenance and repair operations. Representative work includes a $32,620 firm fixed-price delivery order from the Defense Logistics Agency Land and Maritime for input module seals awarded June 23, 2026, a $50,800 purchase order from DLA Land and Maritime for six units of input module seals awarded May 7, 2025, and a $31,400 delivery order from DLA Aviation for MGB tie rod tools awarded August 22, 2024. The vendor's product portfolio centers on NAICS 339991 (Gasket, Packing, and Sealing Device Manufacturing) and related mechanical hardware, with PSC codes spanning packing and gasket materials, bolts, and airframe structural components.

Customer concentration sits heavily with Defense Logistics Agency divisions and the Department of the Navy. DLA Land and Maritime leads by potential value with 20 awards worth $1.6 million combined, followed by Naval Supply Systems Command with 22 awards worth $1.4 million combined, and DLA Aviation with 18 awards worth $1.1 million combined. These three customers account for 60 awards (70% of the portfolio) and $4.1 million (82% of combined potential value). The Navy's Naval Air Warfare Center and DLA Troop Support Hardware round out the active set, collectively representing 83% of awards by count.

Mas Mechanical Solutions holds five active single-award indefinite delivery contracts with DLA divisions. The largest are three Land and Maritime IDCs with $350,000 ceilings each, awarded March 31, 2026, April 30, 2026, and May 28, 2026, respectively, for input module seals with one-year terms and estimated three to four orders per year. A $250,000 IDC with DLA Aviation awarded August 20, 2024, for MGB tie rod tools carries an ultimate completion date of August 19, 2025. An earlier $250,000 Land and Maritime IDC for input module seals, awarded July 14, 2022, with an ultimate completion date of July 14, 2023, is being wound down. Task orders against these IDCs have ranged from $3,250 to $50,800 per order. The vendor also places work under Navy-held parent vehicles including N0010406DL004 (10 task orders, $771 thousand combined potential value) and N6833510D0013 (4 task orders, $377 thousand combined potential value).

Activity has remained steady across the past five years, averaging six awards annually, with recent execution spanning 2022 through June 2026. Only one award carries an ultimate completion date inside the next twenty-four months, representing $33 thousand in recompete exposure. The vendor operates entirely as a prime contractor (100% of awards); no subcontract footprint is present in the source data. Mary ANN Sinde has held SAM registration since 2001, establishing Mas Mechanical Solutions as an established supplier to military logistics infrastructure with demonstrated capability across exacting defense procurement requirements.
