an externally threaded fastener, with a trimmed, square shaped external wrenching head. used in applications where the use of power tools is impractical or undesirable. Offers greater bearing area for more positive gripping with a hand wrench.  grade: ss 304 grade ss 316 high tensile gr. 8.8 / gr. 10.9 mild steel gr. 4.6 / gr. 5.6

Split lock washers provide greater bolt tensioning for tighter assemblies and provide protection against loosening resulting from vibration. Lock washers can be used with a standard washer to provide uniform bearing surface. These washers are unhardened and intended for general use.

An externally threaded fastener with metric threads, a cylindrical head with a flat chamfered top surface, knurled cylindrical sides, and a hexagonal recess. Generally manufactured in accordance with DIN Standard 912 or ISO Standard 4762. Ideal for precision assembly work with close tolerances and applications needing a well tooled appearance. Supplies greater tensile strength than equivalent sizes of hex cap screws while requiring less surface area or counter-bore since the fastener is internally wrenched.

A six-sided internally threaded fastener with metric thread pitch. 16 millimeter nuts and smaller are chamfered on the top and the bearing surface. Larger nuts may be double chamfered, or have a washer face on one side and a chamfered surface on the opposite side. Generally manufactured in accordance with DIN Standard 934 or ISO Standard 4032. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

A six-sided nut with a nylon-filled collar at its back end and metric thread pitch. When a bolt or screw reaches the collar, the threads and nylon form a tight, frictional fit, restricting movement of the fastener when it is subjected to vibration. Generally manufactured in accordance with DIN Standard 985. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

metric hex bolts , partially threaded ( din 931): a hex machine bolt with metric thread pitch. Generally manufactured in accordance with din standard 931 or iso standard 4014 an externally threaded fastener, with a trimmed hex head, but with no washer face on the bearing surface. (its body tolerances are not as close as those of a hex cap screw.) used in a variety of general purpose applications (depending on the grade of the material) in situations where dimensional tolerances are not as critical.  grade: ss 304 grade ss 316 high tensile gr. 8.8 / gr. 10.9 mild steel gr. 4.6 / gr. 5.6

A six-sided internally threaded fastener which is thinner than the thickness of a finished hex nut. Used in combination with a finished hex nut to keep the nut from loosening. Hex jam nuts are thinner than a standard hex nut but have the same dimension across the flats and corners. Hex jam nuts have two common applications. A jam nut can be threaded onto a bolt and run tight against the standard nut which will lock the nut in place and prevent it from backing off. Jam nuts are sometimes used for leveling purposes as well. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

A heavy hex nut made of alloy steel, manufactured in accordance with ASTM Standard A194 Grade 2H. Used for high-temperature and high-pressure conditions. Heavy hex nuts are slightly larger and thicker than standard (finished) hex nuts. There are numerous grades and the heavy pattern is typically used for large diameter and high strength bolts. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

a bolt having a forged head in the form of an open or closed anchor ring. Shoulder pattern eyebolts have an unthreaded shoulder below the anchor ring which is greater in diameter than the threaded shank. used in applications where a forged shank is required, e.g., in rigging when mounted atop a uniformly distributed weight.  grade: ss 304 grade ss 316 high tensile gr. 8.8 / gr. 10.9 mild steel gr. 4.6 / gr. 5.6

A six-sided, double chamfered nut that is available in various widths and lengths. Hex couplers are used to connect two pieces of threaded material. Hex and heavy hex couplers are threaded right hand. If a right hand-left hand coupler is needed, consider using a sleeve nut. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

A round head bolt with a square neck under the head and a unified thread pitch. Designed to keep the bolt from turning when a nut is being tightened. The short neck variety is used in sheet metal where a standard sized neck would create an obstruction.  GRADE: SS 304 GRADE SS 316 HIGH TENSILE Gr. 8.8 / Gr. 10.9 MILD STEEL Gr. 4.6 / Gr. 5.6

METRIC HEX BOLTS, FULLY THREADED (DIN 933): A hex machine bolt threaded to the head with metric thread pitch. Generally manufactured in accordance with DIN Standard 933 or ISO Standard 4017 Hex bolts (six sided heads) are the industry standard for fasteners with forged heads. ASTM A307 grade A bolts, all SAE hex bolts, and several other common specifications require a standard (finished) hex head. For specifications such as A307 grade B, A325 and A490 that require a heavy hex pattern, refer to dimensional tolerances for heavy hex bolts or structural bolts.  GRADE: SS 304 GRADE SS 316 HIGH TENSILE Gr. 8.8 / Gr. 10.9 MILD STEEL Gr. 4.6 / Gr. 5.6

METRIC HEX BOLTS , PARTIALLY THREADED ( DIN 931): A hex machine bolt with metric thread pitch. Generally manufactured in accordance with DIN Standard 931 or ISO Standard 4014 Hex bolts (six sided heads) are the industry standard for fasteners with forged heads. ASTM A307 grade A bolts, all SAE hex bolts, and several other common specifications require a standard (finished) hex head. For specifications such as A307 grade B, A325 and A490 that require a heavy hex pattern, refer to dimensional tolerances for heavy hex bolts or structural bolts.  GRADE: SS 304 GRADE SS 316 HIGH TENSILE Gr. 8.8 / Gr. 10.9 MILD STEEL Gr. 4.6 / Gr. 5.6

looks like a hex nut with an acorn-shaped top. used to cover exposed, dangerous bolt threads or to add a finished appearance all nuts are available in 304, 304l, 316, 316l , h.t gr. 8 , 10 , etc...

A six-sided internally threaded fastener whose thickness is .875 times the nominal nut size and whose width across the flats is 1.5 times. Hex nuts (also referred to as finished hex nuts) are available in ASTM A563-A and compatible with low carbon steel bolts such as ASTM A307, ASTM F1554 grade 36, SAE grade 2, and AASHTO M183. SAE grade 5 and grade 8 nuts are also available in a finished pattern. The most commonly used general purpose nut. All Nuts are available in 304, 304L, 316, 316L , H.T Gr. 8 , 10 , etc...

Has a similar thread design as a metric socket head cap screw. However, the dome-shaped head is wider and has a lower profile than a metric socket head cap screw. Generally manufactured in accordance with ISO Standard 7380. Used when a wider bearing surface or a smoother, more finished appearance is desired. Button head cap screws do not afford the strength of socket head cap screws and are designed for light fastening applications. They are not recommended for critical, high-strength applications.

A headless screw threaded the entire length, with a hexagonal drive at one end and a point at the other end (e.g., cup, half dog, oval, flat, and cone). Used for internal wrenching and where frequent disassembly or adjustment occurs.

Washers provide a smooth bearing surface and are used under the head of a bolt and / or a nut. Flat washers are covered under the DIN 125 A / DIN 125 B standards. These washers are unhardened and intended for general use.
