Bolts

Carriage Bolts

Carriage bolts have a unified thread pitch feature a small, square neck section under the head to prevent the bolt from turning as the nut tightens. We stock stainless steel, medium carbon, and low carbon carriage bolts, including unplated, zinc-coated, and hot dip galvanized options. Select from sizes up to ¾-10 and lengths up to 14”.

Elevator Bolts

Elevator bolts have a shallow conical bearing surface with a square neck under the head and a unified thread pitch. We stock Grade 1 plain and RoHS compliant zinc coated bolts in sizes up to 3/8”-16 and lengths up to 3-1/2” (Ft).

Eye Bolts & U-Bolts

Our extensive bolt inventory includes non-shouldered and shouldered eye bolts and round or square bend U-bolts in several sizes and materials. We stock inch and metric sizes in all the standard materials, including zinc-plated and galvanized steel bolts.

Hex Bolts

Hex Bolts are different then hex cap screws as they are hot forged and not cold headed. They also do not have the tight tolerances of hex cap screws but are highly used in the construction industry because of their mechanical properties.
 
Heavy-duty hex bolts have external threading and feature an oversized, six-sided head to provide a greater wrenching area. Select from hundreds of options including plain, RoHS Complaint Zinc Clear or Hot Dip Galvanized plating. ASTM A193, ASTM A307 Grade A, and Grade B7 bolts available.

Hex Lag Bolts

Hex Lag Bolts are full-bodied bolts with a hex head, spaced threads and a gimlet point. The Hex Lag Bolt is ideally a longer and stronger version of an ordinary wood screw, just larger in diameter and length. We offer hex lag bolts in diameters from 1/4" to 3/4" diameter and lengths up to 24”.

Hex Tap Bolts

Hex tap bolts have a hex head and are fully threaded with a machined point. Our bolt inventory includes stainless steel, ASTM A307 Grade A low carbon, and ASTM A307 Grade 5 medium carbon with an option of plain or RoHS compliant zinc clear coating. We carry sizes up to 1 ¼ -7 and lengths up to 6 ½”.

Plow Bolts

Plow Bolts feature a countersunk, flat head, along with a square neck and a unified thread pitch. We carry Grade 5 Plow Bolts made from medium carbon steel with a core hardness of Rockwell C25-C34.

Serrated Flange Bolts

A Serrated Hex Flange Bolt is an unslotted hex head screw with a unified thread pitch and a flange that has serrations under the head or on the bearing surface side. Serrated hex flange bolts are designed for use in applications where loosening forces are present, such as vibration.
The serrations grip to the bearing surface so that significantly more torque is needed to loosen than to tighten the screw. The flange provides more strength than a standard machine screw, eliminating the need for a lockwasher or locknut in certain applications. We carry Grade 5 hex head serrated crews in sizes up to 1/2”-13 and lengths up to 3” (Ft).

Square Head Bolts

Square head bolts are fully threaded and feature a square wrenching head for greater bearing surface. Our inventory includes low and medium carbon steel A307 Grade A bolts in sizes up to 1” and lengths up to 12”.

Structural Bolts

Structural Bolts, also called "TC" Tension Control Bolts, follow ASTM A325 and ASTM A490 specifications. This three-piece fastening system consists of 1) a round-head bolt with a truncated, flat surface area at the top, and a 24-sided tip which protrudes from the opposite end. The tip is calibrated to shear off when the proper tension is achieved; 2) a 2H heavy hex nut, and 3) a structural washer. Structural bolts are commonly used in structural steel joints in heavy construction.

Timber Bolts

Timber bolts have a round, dome-shaped head and four fins that sink into the material surface at the nut tightens. We carry ASTM A307 Grade A, with a hot dipped galvanized finish in sizes up to 3/4”-10 and thread lengths up to 26”.
