A spring arm sleeve, with which a joining element of a joining device is positionable and which comprises the following features: a tubular section which is formed by a circumferential or all-round wall, the circumferential wall comprises in the circumferential direction a plurality of U-shaped apertures regularly spaced apart from one another, which form a plurality of one-sidedly fastened spring arms which are inclined radially inwards into the tubular section and extend from a fixed end in a first longitudinal direction.

A nail tip guide tool is attached to an end of a nose of a nailing machine to provide guide pieces on a bottom surface inside same, the nail guide tool having a lower portion in a funnel shape. The top surfaces of the guide pieces have a recess in a mortar shape when brought together at the center of the funnel shape by a press board member biased by a coil spring. The guide pieces are used so that in the nose, the tip of a nail in an inclined posture is guided to a center of the mortar shape and is inserted thereamong, and correcting the posture thereof. For fastening a metal piece with a nail, distal ends of the guide pieces are structured to form a conical shape, and with this portion having been fitted into a pilot hole of the metal piece, the nail is struck.

A concrete nailer has a cutout defined by a magazine. The cutout is disposed proximate the drive track of the concrete nailer and provides the concrete nailer with sufficient reach to perpendicularly nail a complete range of U-shaped channels or track available to the job site against concrete, even though the magazine accommodates both long and short nails. The concrete nailer has the added ability to nail thick boards like 2×4's to concrete.

A portable item carrier and belt feed system is provided along with related methods. One illustrative embodiment includes a carrier and feed structure comprising a semi-rigid material with a divider support extending perpendicularly from a center floor section of the carrier. A belt of items is folded over the divider to reduce jams or misfeeds as the belt of items is pulled through a feed chute near an upper side section of the carrier and feed structure at a predetermined range of feed angles to the divider support. A latch disposed on a lid of the feed structure is configured for quick and easy access to the belt of items. A flexible outer container encloses the carrier and feed structure and can be coupled to a harness section configured to couple with a mobile structure. Additional embodiments include variants suitable for field manufacturing as well as portable manufacturing systems and methods.

A spare staple storage device including a housing, a retaining mechanism, an end cap, a first magnet, and a second magnet. The housing having a first end, an opposing second end, and being adapted to secure to a stapler. The retaining mechanism carried by the housing and having a first end, adapted to selectively occlude a first opening at the first end of the housing, and an opposing second end. The end cap secured to the second end of the housing. The first magnet secured to the retaining mechanism at the second end of the retaining mechanism. The second magnet carried by the end cap and positioned to attract the first magnet and retain the retaining mechanism is in a closed configuration.

The present disclosure is directed to a single-sided deck clip that allows an approach to deck board installation with hidden fasteners, and without grooving both edges of a deck board. By not grooving edges, perimeter trim can include one square finished edge on ending pieces. The single-sided clip allows for attaching fasteners through the clip at an angle that penetrates both a deck board and an underlying joist, thus providing a positive connection of decking to joist framing below. In another embodiment, a clip magazine is disclosed that stores, supplies, and assists in installation of single-sided deck clips and fasteners. The clip magazine can hold a plurality fasteners and single-sided deck clips. The magazine allows the single-sided clips and fasteners to be positioned relative to the deck board, and allows fasteners to be aligned with a single-sided clip, and pushed into a deck board during installation.
