Elevator Bolts
Elevator bolts have a flat low-profile head covering a square section, which locks in the substrate.
No. 7 Head Plow Bolts
No. 7 head plow bolts are used in agricultural or snow removal applications where heads need to be flush in order to reduce friction of the plow through soil or snow. They have a point feature for possible shear force breakage to protect the connected machinery.
Step Bolts
Step bolts have a rounded low-profile head covering a square section, which grips the substrate as the assembly is tightened.
Hex Flange Screws with or without serrations
The flange on hex flange screws distributes the pressure over a larger surface area. Serrated options increase friction. Often used with sheet metal.
Liner Bolts
Liner bolts are often used in machinery, such as rock crushers, where the head of the bolt needs to be flush with the liner.
Countersunk Head Machine Bolts
Countersunk head machine bolts are often used in rock crushers, where the head of the bolt needs to be flush with the liner. A variety of head shapes and drives are available.
Askew Head Bolts
Askew head bolts are structural bolts for places that require an angled head contact area, such as in electrical towers.
Round Head Rib Neck Carriage Bolts
Rib neck carriage bolts have several longitudinal ribs below the head, which grip the metal substrate as the assembly is tightened.

Dome Head Scraper Blade Bolts
Dome head scraper blade bolts are for heavy machinery and the attachment of blades where low friction is required, such as in tumblers or to attach snow removal blades.
No. 3 Head Plow Bolts
No. 3 head plow bolts are often used in agricultural or snow removal applications where heads need to be flush in order to reduce friction of the plow through soil or snow.
No. 4 Head Plow Bolts
No. 4 head plow bolts are often used in agricultural or snow removal applications where heads need to be flush in order to reduce friction of the plow through soil or snow.
No. 6 Head Plow Bolts check on tang
No. 6 head plow bolts are used in agricultural or snow removal applications where heads need to be flush in order to reduce friction of the plow through soil or snow. They have a point feature for possible shear force breakage to protect the connected machinery.
Flange 12-point Screws
Flange 12-point screws have 12 points to allow tightening in restricted torque application angles. These screws are typically made in high-resistance metals.
Hex Head Cap Screws "Lamalloy" L-9
Hex head cap screws that carry the "Lamalloy L-9” designations are some of the highest-quality bolts available.
