Armstrong Tools是一家美国工业手工具制造商。在最后几年，它作为Apex Tool Group，LLC的品牌存在，并在美国制造了大部分工具，主要集中在航空航天，政府和军事用户。

Armstrong Tools成立于1890年，由四位Armstrong兄弟在伊利诺伊州芝加哥市的Armstrong兄弟工具公司成立。这对兄弟制造了自行车零件和工具，用于修理和制造兄弟俩后院棚的自行车，并在芝加哥市中心经营一家零售店。

1895年，Armstrong Tools推出了一种用于车床切削刀具的刀架。该产品不是使用单独的锻造切削刀具，而是使用带有可互换切削刀头的单一锻造刀柄，大大降低了这些钻头的成本。该产品的成功让Armstrong Tools于1900年在芝加哥建立了一家工厂（随后在1905年建立了一家更大的工厂）。 1948年，公司迁至现有工厂，并于1974年在阿肯色州费耶特维尔开设了第二家工厂。

1994年，Armstrong Tools被丹纳赫公司收购，该公司作为其工业手工具部门运营。

2010年，作为丹纳赫工具集团的一部分，Armstrong Tools成为Apex Tool Group，LLC的一部分。 2017年，Apex宣布将在南卡罗来纳州萨姆特工厂裁员170名员工，并在3月31日前停止生产Armstrong和Allen品牌。

Armstrong Tools was an American industrial hand tool manufacturer. In its final years, it existed as a brand of Apex Tool Group, LLC and manufactured the majority of its tools in the United States, focusing mostly on aerospace, government, and military users.

Armstrong was founded in 1890 as the Armstrong Bros. Tool Company in Chicago, Illinois by the four Armstrong brothers. The brothers manufactured bicycle parts and tools for repairing and manufacturing bicycles from the brothers' backyard shed and managed a retail store in downtown Chicago.

In 1895, Armstrong introduced a tool holder for lathe cutting bits. Rather than individual forged cutting tools, this product used a single forged shank with interchangeable cutting bits, drastically reducing the cost of such bits. The success of this product allowed Armstrong to build a factory in Chicago in 1900 (followed by a larger factory in 1905). In 1948, the company moved to its current facility, and in 1974, it opened a second facility in Fayetteville, Arkansas.

In 1994, Armstrong was acquired by the Danaher Corporation, where it operated as its industrial hand tools division.

In 2010, Armstrong, as part of Danaher Tool Group, became part of Apex Tool Group, LLC. In 2017, Apex announced that it would layoff 170 workers at its Sumter, South Carolina plant and cease production of the Armstrong and Allen brands by March 31st.
