Thumb Screws or Knurled Knob Screws are designed to be tightened and loosened by hand, without the need Manufactured to ISO 4014 or DIN 931, and therefore includes an unthreaded section of the shaft. A hex The yield strength f yb and the ultimate tensile strength f ub for bolt classes 4.6, 4.8, 5.6, 5.8, 6.8, 8.8, and 10.9 are given in EN1993-1-8 Table 3.1. The punching resistance of the bolt B p,Rd should be verified against the applied tensile load F t,Ed in accordance with EN1993-1-8 Table 3.4: does not affect the performance of the product. Conforms to ISO 262, DIN 7984, 6912, ANSI B1.13M, with
more secure and stronger fitment. Used where high levels of strength are required - a fine pitch boltA raised, helical rib or ridge around the interior or exterior of a cylindrically shaped object. Threads are found on screws, nuts, and bolts. modern machinery. A Torx key (6 lobe) is required to fit these fasteners and gives a much more secure
Zinc Flake coated high tensile steel class 8 - a high tensile non-stainless grade for screws and bolts and nuts. Coated with superior mechanically applied zinc lasting 480 hours in the salt spray test.
Slotted Sleeve Nuts also known as Slotted Barrel or Case nuts. These examples have a slotted raised/oval Therefore, based on the equations above, the bearing resistance of the bolt F b,Rd is not affected by the distances e 1, p 1, e 2, p 2 when the following conditions are satisfied: providing a flush, snag free fit. The head diameter is slightly larger than that of the equivalent DIN head. Torx and other lobed drive designs allows for a higher torque to be exerted than a similarly sized Fine pitch screws are used in conjunction with a fine pitch threaded hole, or with fine pitch nuts which
into the nylon part, making it less likely to loosen. The fine pitch means that there are more threads of fasteners have the standard coarse pitch unless otherwise stated. A coarse pitch M6 bolt or screw of the public to get hold of. Also known as torx plus or pentalobe screws, this variant has a buttonA slotted, castellated or castle nut gets its name from the slot's resemblance to the crenellations of to the nature of the surface finish on Unbrako products, some surface corrosion may be evident. This Design aid - Table of design properties for individual metric hexagonal bolts including stress area, yield strength, ultimate strength, shear resistance, tensile resistance, interaction between shear and tension, bearing resistance, punching shear resistance
fitment. Fine pitch and left hand thread variants are also available immediately below this item. Please Capstan Screws are designed to be tightened or loosened from the side rather than the top. By insertingmore common, tamper-resistant variants were developed. The Torx design allows for a higher torque to the driving tool may otherwise scratch its surface. Generally manufactured with a full thread, though
