#HARBOR FREIGHT IMPACT DRIVER BITS SET OF 4 ISO#
ISO 2380-1 specifies the internationally standardized shape and dimensions of the tips of screwdrivers for slotted-head screws as well as the minimum test torque the blade-to-handle connection shall withstand. Note that it is this typical chisel shape which allows 9 screwdriver sizes to drive 24 different slotted screw sizes, with the drawbacks of not fitting as closely as a hollow-ground screwdriver would, and increasing the possibility of damaging the fastener or surrounding area. Flat-blade jeweler's screwdrivers and the tips found in 1⁄ 4-inch or 6.4-millimeter drive sets are generally hollow-ground. A hollow-ground screwdriver is less likely to cam out (leave the slot due to the torque being translated into an axial force, similar to that encountered with Phillips drive but dependent only on driver blade), so more torque can be applied without damaging the screw head. The tool used to drive a slot is called a common blade, flat-blade, slot-head, flat-tip or flat-head / flathead screwdriver. For this reason, cruciform-slotted along with drives have replaced the slot drive in numerous applications. However, this design is not well-suited for installation by power tools, given that a power driver often slips out of the slot this often causes damage to the screw and surrounding material. Slot screws are also used in the restoration of antique furniture, vehicles, and equipment. The slotted screw is commonly found in existing products and installations, along with use in simple carpentry work and in applications where minimal torque is needed. Additionally, it is unique compared to other common drives, due to it being straightforward to manufacture the slot head, and the ability to be driven by a simple handtool.

This form was the first type of screw drive to be developed, and for centuries, it was the simplest and cheapest to make. Slot screw drives have a single horizontal indentation (the slot) in the fastener head and is driven by a "common blade" or flat-bladed screwdriver. Standard slot screwdriver sizes (ISO 2380). That organization is a very very large Amazon seller I’m talking top 200.Slotted drives Slot drive tool and screw sizes Blade width About a year later we just caught off all e marketplace sellers. Some of our customers started selling on Amazon (drop shipping from us) when we finally got our s*** together we just attached to their listings undersold them. I worked for a large company that had a lot of licensed apparel. Once an Amazon listing is made for a product that is mostly the hard part anyone that has the product an Amazon account can hook onto it and sell the product. This leads me to believe harbour freight does wholesale to people and or someone’s buying a boat load of harbor freight load in the back of trucks and then selling it online. More interesting to me is that there are five sellers that sell it.

Speaking of which, Amazon has a competitively-priced “ships from and sold by ” listing for a Milwaukee cordless impact wrench and grease gun combo.ĭoes anyone have any concrete insights into how or why this happens? I had similar questions about how Amazon and Walmart were directly selling select Milwaukee Tool products, and I still don’t have any better of an understanding. Or, maybe they were… somehow… coming from 3rd party sellers? Perhaps Harbor Freight is shipping some tools to Amazon to help increase the familiarity of their brand names, or maybe Amazon is buying the tools from Harbor Freight at retail and is listing as part of some search engine traffic strategy. I can only think of two potential explanations. Why does Amazon have these Harbor Freight tool listings? How? Some of the items are said to be in low supply, but others are in low supply with “more on the way.” There, you’ll find things like a Central Forge clamp-on swivel vise, at 2X Harbor Freight’s direct price, or a Banks brad nailer at a ~75% markup. The brand is said to be Central Purchasing, and following that trail leads me to 55 search results for Central Purchasing tools sold directly by Amazon. More Info: Hercules Drill Bit Set on Amazon, the same drill bit set at Harbor Freight. Whenever I ask this question of brands that don’t usually distribute through Amazon, the first response usually goes like this: “oh, that’s a 3rd party listing.” But, in this case and some others, it’s not. How are they selling this Hercules drill bit set directly?
