Marine Grade Fastenings

Commonly referred to as a setscrew or simply as a bolt. The fully threaded DIN 933 or ISO 4017 should not be confused with its DIN 931 equivalent. A standard spanner or ratchet is typically used to fit this product. Used for decades on all types of assembly throughout the world. As with the DIN 931 hex bolt, the hex drive allows a higher torque to be applied. All parts are to DIN 933 except where shown otherwise. The alternative standard ISO 4017 specifies differences in head dimensions for M10, M12 and M14 thread diameters from DIN 933. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Commonly referred to as a setscrew and longer versions are referred to in the United States as a tap bolt. A standard spanner or ratchet is typically used to fit this product. Used for decades on all types of assembly throughout the world. The hex drive allows a higher torque to be applied. Produced to ASME B18.2.1.

The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner or ratchet and socket. Popularly used in all assemblies, a standard hex bolt is a staple across the world. Manufactured to ISO 4014 or DIN 931, and therefore includes an unthreaded section of the shaft. A hex drive permits a greater torque load to be applied to the joint over most other drive types.

The most common type of fastener, a hex head bolt is designed to be tightened with a standard spanner or ratchet and socket. Popularly used in all assemblies, a standard hex bolt is a staple across the world. Manufactured to ASME B18. 2.1, and includes an unthreaded 'shoulder' or portion of the shank. A hex drive permits a greater torque load to be applied to the joint over most other drive types.

Also known as an Allen screw or Allen bolt, or simply a cap screw. Socket Head Cap screws are a more modern alternative standard machine fastener to the standard hexagon headed bolt or setscrew, as found on much modern machinery. A hex key (otherwise known as an Allen key) is required to fit these fasteners. Conforming to DIN 912 or ISO 4762. Please note that due to manufacturing limitations, all nylon variants of these items are only "similar to" and not "in absolute accordance with" the standard specified.

Also known as an Allen screw or Allen bolt, or simply a cap screw, socket head cap screws are a more modern alternative standard machine fastener to the standard hexagon headed bolt or setscrew, as found on much modern machinery. A hex key (otherwise known as an Allen key) is required to fit these fasteners. Conforming to ASME/ANSI B18.3, the contact surfaces of this screw or bolt are protected from external damage. Generally manufactured with a partial thread beyond a certain length and nominal diameter combination, but occasionally some stock may include a fully threaded shank at the same combination.

Fine pitch screws are used in conjunction with a fine pitch threaded hole, or with fine pitch nuts which are also available on this website. The extra thread engagement gained from the finer pitch gives a more secure and stronger fitment. Used where high levels of strength are required - a fine pitch bolt has a larger stress area creating better tension than its coarse pitch counterpart, also they are less inclined to loosening through vibration due to the thread incline being smaller.

Similar to the DIN 912 socket cap screw but with a lower head height and smaller hex drive, the DIN 7984 is used where space is limited. This range is generally manufactured with a partial thread beyond a certain length and nominal diameter combination, but occasionally some stock may include a fully threaded shank at the same combination.

A popular and attractive socket head screw, typically used where aesthetics are important, or where a lower profile domed finish is required. The hex drive is generally smaller than other hex driven ranges and thus the ultimate tightening torque is reduced. Manufactured to ISO 7380, and almost always fully threaded.

A countersunk headed screw conforming with ISO 10642 or DIN 7991, requiring a hex key (otherwise known as an Allen key) to fit. The countersunk head is typically used in conjunction with a countersunk hole providing a flush, snag free fit. Generally manufactured with a full thread, though occasionally some stock may include a partially threaded shank. The head diameter is slightly larger than that of the equivalent DIN 965 Phillips or Pozi driven screw.

These attractive 5-Lobe Pin security machine screws offer an improved tamper resistance compared to the more commonly available 6-Lobe Pin drive. The tooling is therefore more specialised and harder for members of the public to get hold of. Also known as torx plus or pentalobe screws, this variant has a button head. Torx and other lobed drive designs allows for a higher torque to be exerted than a similarly sized conventional hex socket head.

Also known as star, 6 lobe, and hexalobular internal. Torx screws are commonly found on cars, motorcycles, bicycle brake systems, hard disk drives, computer systems and consumer electronics and are becoming increasingly popular. Once, they were typically used in applications requiring tamper resistance; as drivers became more common, specific tamper-resistant variants were developed. The Torx design allows for a higher torque to be exerted than a similarly sized conventional hex socket head. Conforms with DIN 7985.

Generally used in timber to timber and timber to metal construction, these bolts incorporate a square neck to grip the hole in the timber when fitting, and therefore negates the need for any drive recess to be included on top of the head. Supplied to DIN 603. Manufactured with a fully threaded shank. Nuts are supplied seperately, unlike the mild steel versions available elsewhere on the site.

Ideal for anchoring hooks, attaching rope wire and cables to solid surfaces, such as wood, metal, concrete, etc. The A4 stainless steel, grade 316-NM give it corrosion resistance and durability, making it perfect for marine, food, medical and pharmaceutical industrial enviroments.

A popular and attractive socket head screw with an integrated flange offering a wider head for bolting softer materials. Typically used where aesthetics are important, or where a lower profile domed finish is required. The hex drive is generally smaller than other hex driven ranges and thus the ultimate tightening torque is reduced. Manufactured to ISO 7380, the same standard as the non flanged variant, and always fully threaded.
