It is available in three different ANSI thread specification standards: UNC (Unified Coarse), UNF (Unified Fine), or UNS (Unified Special). The straight flutes are suitable for threading through holes (extending through the workpiece) and blind or bottoming holes (with only one opening). Right-hand threads are designed to tighten when the head or nut is rotated clockwise (the most common threading direction). High-speed steel (HSS) is a common general-purpose steel for cutting tools and is compatible with a variety of materials. With no coating or surface treatment, this uncoated tool can be used on a broad range of materials and provides an economical alternative to coated tools. The round shank with square end makes it suitable for hand or power-driven applications. This tool can be used in machines, such as drill presses or lathes, or with hand tools such as tap wrenches. In the Union Butterfield 1500(UNC) and 1500(UNS) series, all taps have four flutes. In the 1508(UNF) series, all taps have three flutes. Taps in all series are available with a variety of chamfers. This tap conforms to ANSI standards and can create threads to a depth 1 ½ times its diameter. It is suitable for ANSI 2B and 3B tolerance classes: 2B is an average quality fit for commercial and industrial fasteners; 3B produces close-tolerance fasteners that resist loosening, as in aerospace applications. Taps produce internal threads in previously formed holes and can be used in machines (such as drill presses) or with hand tools. Common types of taps include hand taps, spiral point taps, spiral flute taps, thread forming taps, and pipe taps. Hand taps (straight-flute taps) collect chips in the straight flutes of the tool; spiral point taps push chips through holes ahead of the tool; and spiral flute taps pull chips back from the tip of the tool, up and out the hole. Thread forming taps, also known as cold forming taps, press rather than cut to create threads in a drilled hole, and no chips are created. Pipe taps create threads in pipes and pipe fittings. Each thread type designates a thread profile and each type is identified with an abbreviation. In the U.S. and Canada, the Unified Thread Standard is the dominant thread type, including UNC (Unified Coarse), UNF (Unified Fine), and NPT (National Pipe Taper) threads, among others.

The company has locations around the world, and provides tools adhering to ANSI, NAS, and DIN standards. ## Features - Hand threading tap with straight flutes cuts threads in through holes and blind holes - Available in UNC (Unified Coarse), UNF (Unified Fine), or UNS (Unified Special) right-hand thread options for different applications - High-speed steel is compatible with a variety of materials - Uncoated (bright) tools have no additional surface treatment or coating, suitable for general-purpose applications - Round shank with square end allows tap to be used in hand or power-driven applications ## Images ![Union Butterfield 1500(UNC) High-Speed Steel Hand Tap, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, H5 Tolerance, 3/8"-16 Thread Size - Image 1](https://images-na.ssl-images-amazon.com/images/I/41nnFLFWstL.jpg) ![Union Butterfield 1500(UNC) High-Speed Steel Hand Tap, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, H5 Tolerance, 3/8"-16 Thread Size - Image 2](https://images-na.ssl-images-amazon.com/images/I/31SYVhB3MmL.jpg) ![Union Butterfield 1500(UNC) High-Speed Steel Hand Tap, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, H5 Tolerance, 3/8"-16 Thread Size - Image 3](https://images-na.ssl-images-amazon.com/images/I/511FlWomYoL.jpg) ![Union Butterfield 1500(UNC) High-Speed Steel Hand Tap, Uncoated (Bright) Finish, Round Shank With Square End, Plug Chamfer, H5 Tolerance, 3/8"-16 Thread Size - Image 4](https://images-na.ssl-images-amazon.com/images/I/31Ey%2B2DqqgL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality product, great price! *by R***. on July 29, 2018* A lot smaller than what I imagined, but it's a quality tool and it works as intended just fine. ### ⭐⭐⭐⭐⭐ Worked great, but had to be shortened *by A***M on December 15, 2017* Worked great, but had to be shortened. This is a standard size tap, but for my purposes I needed it to be shorter. Chased a tapped hole in cast iron heads that needed a little cleaning like a champ. ### ⭐⭐⭐⭐⭐ Seemed to stay sharp and cut very easily. *by B***R on August 16, 2016* Used this to tap a hole in 1/4" square tubing. My hole ended up being a little crooked but that was probably an operator error. Seemed to stay sharp and cut very easily. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/131187268-union-butterfield-1500-unc-high-speed-steel-hand-tap-uncoated](https://www.desertcart.vn/products/131187268-union-butterfield-1500-unc-high-speed-steel-hand-tap-uncoated) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-20*
